Re: how to provide own out of tree implementation/replacement of existing driver
Bolivar, Marti
Hi,
toggle quoted messageShow quoted text
You should be able to just disable the in-tree driver using Kconfig and use your own out of tree driver. "Jan Pohanka via lists.zephyrproject.org" <xhpohanka=gmail.com@lists.zephyrproject.org> writes:

how to provide own out of tree implementation/replacement of existing driver
Jan Pohanka
Hello,
I would like to use my own implementation of an existing driver. Is there any way to do that? I have found an amend feature in https://github.com/zephyrproject-rtos/zephyr/pull/19980 but I cannot make it work. If I understand correctly it is intended more to add some functionality than completely replace. In my use-case it would be probably easier to use out of tree implementation for some time than maintain patches for the main tree. In fact I need just to add support for new soc from the stm32 family that is not yet in existing drivers (clock, watchdog, ethernet, etc). Later when our code is polished, I will prepare pull-requests. best regards Jan

Git submodules with West
#west
mike@...
Hi,
I have a Zephyr project set up as a manifest repository, and I'm trying to include a git repository that makes use of submodules. i.e., I would normally clone this repository with: git clone --recursiveIs there a way to specify this from west.yml? I was able to manually add the sub-module by specifying a new project containing the sub-module in west.yml, and using the 'path' specifier to put it underneath the top level git repo. But, I'm wondering if there's a way to do this without having to manually add all of the sub-modules to west.yml. Thanks in advance.

Re: BLE "Just-Works" configuration
Jeremy Herbert
I ended up resolving this, it was to do with the previous bond information being stored. The following two configs fixed it: CONFIG_BT_KEYS_OVERWRITE_OLDEST=y CONFIG_BT_SMP_ALLOW_UNAUTH_OVERWRITE=y Note that this is an insecure configuration, CONFIG_BT_SMP_ALLOW_UNAUTH_OVERWRITE allows a possible forced deauth and reauth MITM attack. But for testing it works fine. Thanks, Jeremy

BLE "Just-Works" configuration
Jeremy Herbert
Hi, I'm trying to set up Zephyr as a BLE peripheral with an nrf52810. I have the peripheral_hids example running fine, including bonding with the passkey being printed out over printk. However, my actual end device doesn't have any input/output other than a few buttons, so I'd like to change this to use "Just-Works" pairing so it can at least bond and have encrypted communication but not have MITM protection (ie BT_SECURITY_L2). I can't seem to find much documentation on implementing this scenario using Zephyr, so I was wondering if there is an example available on exactly what to do for this type of pairing/bonding where no input/output is available? I did give it a try myself based on this example, but I am a bit stuck. I have tried setting the bt_conn_auth_cb members all to NULL, as well as changing the GATT entry permissions to BT_GATT_PERM_READ_ENCRYPT instead of BT_GATT_PERM_READ_AUTHEN (I also did the same for the BT_GATT_PERM_WRITE_AUTHEN). When connecting and bonding with an android device (I'm using the nRF connect app), it asks to pair, but then on continuing with this it fails. In the debug log from the device I can see (I removed the MAC address): Security failed: XX:XX:XX:XX:XX:XX (public) level 1 err 4 Disconnected from XX:XX:XX:XX:XX:XX (public) (reason 0x13) where error code 4 is BT_SMP_ERR_CONFIRM_FAILED. I also tried setting a pairing_confirm callback in the bt_conn_auth_cb struct which just confirms the connection by calling bt_conn_auth_pairing_confirm(), but it doesn't appear to make a difference. Any pointers would be appreciated. Thanks, Jeremy

Re: Seeed BLE Micro (nrf51822) hangs on k_msleep
Vinayak Kariappa
Hi Matias, From the schematics posted in seedstudio website, indeed a 32KHz crystal is said to be present. You may always use the internal 32 KHz RC oscillator in nRF51 to check if the system timer is not the problem. Enable the following to use RC Oscillator: CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y CONFIG_CLOCK_CONTROL_NRF_K32SRC_500PPM=y 16MHz clock is essential for 2.4 GHz radio peripheral. Regards, Vinayak

Re: CONFIG_HEAP_MEM_POOL_SIZE
Andy Ross
I thought I fixed the docs, but it looks like that text is in kconfig? The original mem_pool code had a hard requirement that the memory region be a power of four larger than the smallest allocation unit. That was relaxed a while back so that odd sizes would work, though at the cost of some fragmentation. And now the whole mem_pool implementation has been replaced as the default by a newer heap that has more conventional behavior and is more flexible with memory regions and more fragmentation resistant. You have to ask (via kconfig) to get the old backend now, the same API is pointing to wrappers. So yes: pretty much any size will work fine for default code in the current tree. There are a few dragons still though, like the fact that CONFIG_HEAP_MEM_POOL_SIZE is actually padded significantly before it becomes a byte array in your image (because it specifies what in the old scheme was the block of "live" memory, and the old mem_pool would then allocate a completely separate array for metadata that wasn't accounted for).

Re: Use different memory bank
Arvid Rosén
Great!
And yes, those are the old devicetree macros for the same thing. So you can keep the lines I sent as comments in the file until the time you upgrade (but maybe the numbers are different for 1060). Hopefully, we have a better solution for this by then, as the dts_fixup file is deprecated by now.

You solution worked! Thanks! But I had to modify it to work with my code base:
#define ITCM_ADDR (DT_INST_0_NXP_IMX_ITCM_BASE_ADDRESS) #define DTCM_ADDR (DT_INST_0_NXP_IMX_DTCM_BASE_ADDRESS)
I dont know why I had to use a different symbol name than you. Maybe because of Zehpyr version, we use currently 2.2.

Hi Antoine,
We use CODE_DATA_RELOCATION on i.MX RT 1020. It is a bit of a hack though, but I added this to the dts_fixup.h for our board:
// Needed for CODE and DATA relocation #define ITCM_ADDR (DT_N_S_soc_S_flexram_400b0000_S_itcm_0_REG_IDX_0_VAL_ADDRESS) #define DTCM_ADDR (DT_N_S_soc_S_flexram_400b0000_S_dtcm_20000000_REG_IDX_0_VAL_ADDRESS) #define OCRAM_ADDR (DT_N_S_soc_S_flexram_400b0000_S_ocram_20200000_REG_IDX_0_VAL_ADDRESS)
Obviously, this isn’t a good solution, but it does work for us at least.
It would be great with some input on howto solve this for real.

Yes, I've tried that. See in my first post: > - How to specify that code should be relocated to ITCM while using CODE_DATA_RELOCATION ? I have tried "zephyr_code_relocate(ram_func.c ITCM)" but with no success.
As said, I was able to move come code to the SRAM but not to another RAM bank. Also I'm not sure that the BSP for the i.MXRT is doing it right. There is a few more memory region defined in the linker script in "soc/arm/nxp_imx/rt/linker.ld" and I think it is that that is printed at the end of the compilation. I think the related section are missing in the linker file. I don't know if the build system is expected to generate them from "zephyr_code_relocate() " and place them in the right memory region or if I need to do something extra.

Seeed BLE Micro (nrf51822) hangs on k_msleep
Matias N. <matias@...>
Hi, I'm starting a project based on the BLE Micro module from Seeedstudio. Since this "board" was not supported but the RedBear BLE nano board is the most similar one, I created a custom board directory for it using this as a template. I managed to flash the blinky sample to the module (using openocd and a ST-Link v2 clone device) and can also connect with gdb to debug. I have this module soldered to a custom PCB which features a LED and thus I set the correct LED GPIO in the dts file. I managed to control the LED but from my debugging it seems to hang when calling k_msleep(). When it hangs, if I pause the execution it appears to be right after the "wfi" instruction (i'm assuming the debugger breaks the sleep). I'm not sure why this could be happening. My guess it is something to do with the clock configuration. The module features a 32.768hz crystal (just like the BLE Nano) but also a 16 MHz crystal (which I'm not sure is used or not by zephyr). I tried disabling tickless, but the behavior does not change. As I'm new to zephyr I'm not quite sure what else to check. Googling for this problem I found old issues in GitHub relating to tickless mode, low-power, rtc, etc. But all seem to be merged/closed. I would appreciate any help in this. Best, Matias
