Could you please test the PR on your board and let me know if its better.

Find attach the patch file as alternative to the diff in PR. Use "git am <patch file>" to apply the changes on latest zephyr master branch.

Your config file looks ok.

I will check if errata 201 will solve your issues. I will try to send you a patch by this weekend.
As I will need to reproduce the issue, you will need to help me if it is the root cause. (with my DK, I did not see issues for hours before I had to be away from my desk).

__ASSERT - transfer to error handler

kristoffer.skoien@...
 

Current implementation:

The __ASSERT macro is extensively used in the Zephyr code base and in application code for debugging during development.

In case of an ASSERT, the code jumps to __ASSERT_POST which spins the given thread in a while(1).

 

Issue:

During development and debugging, simply looping the thread will mask that the ASSERT has triggered. The only feedback the user gets of an assert is a printout.

This can be missed if e.g.:

- The RTT or Serial debug interface is down or unused

- There is too much logging so that the “ASSERTION FAIL” can be missed

 

Proposed solution:

In __ASSERT_POST provide a function call that will end up a user definable error handler. E.g. _SysFatalErrorHandler()

 

This will let the developer set given SOC pins in case of an ASSERT, ask for a specific LED pattern to be set or print further debug messages.

 

Feedback is appreciated.

 

Kind regards

Kristoffer

Re: NRF52832 - setting up NFFS for the external flash W25QXXDV

Johannes Hutter
 

Hey Faisal,

we recently had trouble with the Winbond driver as well, but in the context of FCB and NVS. Something we found is that the current driver doesn't support writing across write pages. So if you call the write function, but the write would cross one of the write page boundaries, the remaining part on the second page is not written. However, we use a W25QxxFV flash, not the DV, so YMMV. We added PRs for the page layout implementation (https://github.com/zephyrproject-rtos/zephyr/pull/11114) as well as writing across write page boundaries (https://github.com/zephyrproject-rtos/zephyr/pull/11113). Maybe this helps.

Best Regards
Joe

So Zephyr provides the driver for W25qxxdv, but without page layout implementation. I modified the driver by adding page layout support, simply copied from the nrf flash layout implementation.. given the size is 2MB, page size kept to 4096.. makes 512 pages... please correct me if I shouldn't be doing it... If I don't do it then I get kernel panic because there is no implementation. I know that PAGE_LAYOUT should be disabled to avoid it but one of the settings is overriding PAGE_LAYOUT to be activated even if I disable it..

       flash_page_layout_not_implemented,
#else
.page_layout = flash_W25QXXDV_pages_layout,
#endif
#endif
.write_block_size = 1};

I could also see that the nffs_mount function inside nffs_fs.c has hardcoded the flash id to 0.. does it indicate that NFFS is to be implemented only the internal flash... I have disabled that bit here and I am setting  "flash_desc" before entering the function and passing it through the input argument "mountp"... Please correct if my understanding is wrong.. e.g., 
                flash_desc.id = 1;
flash_desc.sector_count = flash_get_page_count(flash_dev);
flash_desc.area_offset = 0; //1044480;
flash_desc.area_size = 1048576;   //even though it is 2MB, I am only using 1MB for now...

static int nffs_mount(struct fs_mount_t *mountp)
{
struct nffs_flash_desc *flash_desc =
(struct nffs_flash_desc *)mountp->fs_data;
int cnt;
int rc;
 
/* Set flash device */
flash_dev = (struct device *)mountp->storage_dev;
 
/* Set flash descriptor fields */
#if 0
flash_desc->id = 0;
flash_desc->sector_count = flash_get_page_count(flash_dev);
flash_desc->area_offset = FLASH_AREA_STORAGE_OFFSET;
flash_desc->area_size = FLASH_AREA_STORAGE_SIZE;
#endif
rc = nffs_misc_reset();
if (rc) {
return -EIO;
}

rc = nffs_misc_desc_from_flash_area(flash_desc, &cnt, descs);

case FS_ECORRUPT:
rc = nffs_format_full(descs);
if (rc) {
return -EIO;
}
break;
default:
return -EIO;
}
 
return 0;}
So I could see that there is no "Lost+Found" directory inside the external flash, and when it tries to create it, it fails while writing.. thus I am getting -5 (EIO) message when I am trying to mount it...
Inside "nffs_restore_full" function, it does nffs_restore_area_contents(..) ... I could see activity on the pins when I probe it.. then it ensures that the file system contains a valid scratch area... then it ensures that the file system contains a valid root directory.. finally when it is trying to confirm, if there is a lost+found directory,.. which is not there, so it tries to create it and in turn writes to it, which fails... and it fails to mount...

I can easily upload and download a file into the internal flash via mynewt from our mac computer, size around 23k. I had to reduce the maximum data chunk size for file upload and download from 512 to 256 or else it would give me errors and would never finish the transfer... Now I want to store images into the external flash which is why i need to setup NFFS on it..

【HCI_UART】hci_uart sample cannot advertise controlled by HCI commands #nrf52832 #uart #hci

icephyr
 

Hi guys, I met a problem with official hci_uart sample. Hope anybody can give me any advice,thanks.

I use NRF52832's official develop board running hci_uart sample as a controller, I send hci commands to it to make it advertise outside, also I open btmon to observe the process. It seems worked and output like this below. But I did not find the packet when I use my cell phone to scan the advertise packet. So my question is, Does hci_uart sample support the advertise function ? Any methods can help to resolve this problem ? Thanks

Hey guys,

I'm tryinig to create an external counter on nrf52 for 10MHz using PPI, GPIOTE and time counter but I don't know where I'm doing it wrong. Follow my code so far. The commented part is just a test I did with interruption to test the hardware, obviosly it won't reach the required 10MHz.


If anyone has any inputs would be very helpfull.

refer to the following code you shared.

Check the smp server sample here: https://github.com/zephyrproject-rtos/zephyr/tree/master/samples/subsys/mgmt/mcumgr/smp_svr

And the corresponding Android libraries here: https://github.com/runtimeco/mcumgr-android

 

I am aiming to send a file from mobile to BLE and ultimately to transfer the file to UART.

 

smp_svr Is this code the AP code or the hex code that I need to put in Nordic?

 

I do think, I need both Nordic code and AP code.?

 

Thanks you

Hi there,

 

I believe mcumgr will allow you to do what you need.

Check the smp server sample here: https://github.com/zephyrproject-rtos/zephyr/tree/master/samples/subsys/mgmt/mcumgr/smp_svr

And the corresponding Android libraries here: https://github.com/runtimeco/mcumgr-android

Subject: [Zephyr-devel] [Question] zephyr file transfer via BLE

 

Hi, This is seungwoo

 

I have a question

 

If you look at the site below, I can transfer BLE file using Nordic chip.

https://devzone.nordicsemi.com/f/nordic-q-a/33093/transfer-big-file-over-ble

 

nrf52-ble-image-transfer-demo çè Android-Image-Transfer-Demo   // file transfer

 

I am trying to develop a device with BLE functionality using nrf52810 in zephyr OS.

 

Like nrf52-ble-image-transfer-demo, Can I use zephyr with an application that can transfer files with Android?

 

Or I would like to ask if there is a case in which Zephyr tried to implement file transmission via BLE.

 

Thanks you

Andrezej, thanks for looking at this.  To keep things simple, I went back to the sample project:

With the exception of adding the first line, I don't believe I have changed anything from the zephyr clone I
made a few weeks ago (1_13_99).  Here's the prj.conf.

I know echo_server does not require newlib; but my app may.  This is the same behavior I see in my project.
Thought focusing on a sample project would help keep things a bit clearer.

Hi

 

I’m unable to reproduce this problem – I mean that I did not encounter problem compiling usbd along with newlibc.

Can you point prj.conf you used, or even the project?

Well, as is usually the case, as soon as I'm convinced I'm stuck and send off a note, I try something else and make a bit
of progress......sigh.  The new project I was trying to integrate with an ecm usb network device interface had the following in prj.conf:

CONFIG_NEWLIB_LIBC=y

As soon as I removed that line, nrfx_usbd.c compiled - as did everything else.  The requirement for newlib may have been historical
and possibly irrelevant now.  I was doing some testing with a 3rd party source code package.  But, I don't know if this constitutes an
issue with the newlib code in the present distribution (1_13_99).  Can't say that my code is now functional, but the bizarre compiler behavior has disappeared. 
So, I think an interaction with the current newlib code is the cause of my initial problem.

Any comments on this are appreciated.  I may need newlib for compatibility reasons later on....would like to understand what's going on
here.

usb device network on nrf52840 platform

Has anyone had any luck adding usb device networking to a project outside of samples/net/echo_server ?
I have built the above project with -DCONF_FILE="prj.conf overlay-netusb.conf" and it appears to work correctly.
But, when I add the overlay-netusb.conf file to another project - in particular, samples/net/sntp_client, the file nrfx_usbd.c
fails to compile.

The compile problem shows up when compiling nrfx_usbd.c (which compiles fine in the echo_server project).  There are
a number of complaints; but I suspect they have the same root cause - undiscovered as yet!

From what I can see, macro processor can't find a symbol it needs for evaluation.  I think most of the include files are actually static and not created by cmake.
So, I don't expect any problems there. The .config files generated for both projects are the same viz. networking and the generated dts .h files for both projects are identical.

Has anyone integrated USB device networking into a non sample project.

Hi,

As announced a few weeks ago, we have been working on a new version of the SDK with updates mostly to the host tools.

This release of the SDK has the following changes as compared with 0.9.3:



· New QEMU release (based on 3.0.0+git 19b599f7664b2ebfd0f405fb79c14dd241557452)

· Qemu installation now has all needed ROMs and BIOS files to support connecting Ethernet drivers such as the Intel e1000.

· New OpenOCD based master with Zephyr related changes (commit: 05e0d633)

· New DTC version 1.4.7+git (commit 2e930b7f8f6421638869a04b00297034c42e1a82)

· Upgrade arc binutils to 2018.03-rc2



The above changes and especially the Qemu related items require that you move to the new SDK ASAP, earlier version will not work with the master tree.

How are Windows and Mac users supposed to update DTC?

- macOS via HomeBrew seems to be on 1.4.7 exactly, and you mention commit 2e930b7, which is ahead of that tag in git://git.kernel.org/pub/scm/utils/dtc/dtc.git
- Windows via chocolatey looks like it's on some v1.4.7 commit that's not in the upstream tree (dtc --version shows "1.4.7-g79c2a3d9-dirty"
on my Windows machine)

Similar questions for openocd; do macOS and Windows users need to build their own? I looked at the openocd commit history around that time and there seem to be some generic RTOS support patches as well as nRF related patches, so I'm curious what windows/mac users are missing out on.

Windows is on 1.4.7 exactly. I created and updated the package myself 2 weeks ago. The dirty is there because there's a patch to make it work on Windows.
OK, thanks. So the dtc question is the same on Windows as on macOS
(and remains open): what should users do to get this latest version?
Will vanilla 1.4.7 continue to work?

Thanks,
Marti
