big_http_download sample localhost download

Brenton Chetty
 

Hello,

I am attempting to download a file hosted on a localhost file server.

- I am hosting a file named "Zephyr" using "python3 -m http.server 8980"
- I am using a zeth interface and the "overlay-e1000.conf" to allow qemu to communicate with localhost. I successfully tested the LWM2M client example to ensure the connection was good.
- I can download the Zephyr file when I input "http://192.0.2.2:8980/zephyr" into a web browser.
- I attempted using the "overlay-ci.conf" file to perform the download.
    CONFIG_SAMPLE_BIG_HTTP_DL_URL="http://192.0.2.2:8980/zephyr"
 however I get the following error:
     Preparing HTTP GET request for http://192.0.2.2:8980/zephyr
     addrinfo @0x6da008: ai_family=1, ai_socktype=1, ai_protocol=6, sa_family=1, sin_port=1423
     Iteration 1 of 1:
     sock = 0
     [00:00:00.000,000] <inf> net_config: Initializing network
     [00:00:00.000,000] <inf> net_config: IPv4 address: 192.0.2.1
     [00:00:00.000,000] <inf> net_config: Running dhcpv4 client...
     Error: connect(sock, ai->ai_addr, ai->ai_addrlen)
     exit

I managed to get the example to download the online vmlinuz file, however I cannot get the sample to download via localhost.
Do you have any suggestions on what steps I could have missed?
Could it be a DNS issue? for downloading the online vmlinuz file I used 8.8.8.8 as CONFIG_DNS_SERVER1. For localhost, I left it at 192.0.2.2

With thanks

Hi,

The counter API provides exactly that: https://docs.zephyrproject.org/latest/reference/peripherals/counter.html

Does Zephyr support USB host mode and also USB-OTG?
If not, is it on the roadmap?
Thanks!

stm32: PWM: "st,prescaler" pwm property moved to timers node

Alexandre BOURDIOL <alexandre.bourdiol@...>
 

Hi all,

 

I'd like to inform STM32 PWM users that I'm pushing a change [1] to move Device Tree property "st,prescaler" from pwm node to timers node.

Benefit is that it reflect hardware reality, and prescaler is usable by  other drivers based on timers (like counter with ongoing PR #39414)

 

This change will be hopefully integrated in the next Zephyr DV.

Note that I temporarily avoid compatibility break:  if "st,prescaler" is defined in PWM node, it will be the value used by PWM driver.

 

[1] https://github.com/zephyrproject-rtos/zephyr/pull/39628

 

 

Regards,

Alexandre Bourdiol

 

 
Re: Setting MAC address at boot? #stm32

Update! Problem solved. The function net_if_set_link_addr() sets the MAC address.

Why isn't the function named net_if_set_mac_addr()?
Re: MCUboot - Signing image for slot 1 #mcuboot

Adam Podogrocki
 

Hi Brenton,

The only images you should flash are MCUboot and an image that goes to Slot#0. Any further operations should be conducted with the mcumgr tool. At least I used to do that. This tool gives you options to upload the new image (the first uploaded image should obviously be the one dedicated to slot#1), list already uploaded images, to check which slot is the current one, to boot from specified slot in test mode and finally to confirm, that the currently run image should become the active one.

This tool performs swapping of images, so this is why you should also have a scratch_partition in your layout, e.g. 
partitions {
  boot_partition {};
  slot0_partition {};
  slot1_partition {};
  scratch_partition {};
  data_partition{}; // remaining space for application data purposes, optional
};
When the image is confirmed, then swapping takes place and always the image from slot#0 is booted.

At the time I used that tool UART and Bluetooth protocol were available.

Cheers,
Adam

Hi Adam

Thank you for your reply. Sorry for the late response, as I have been getting sporadic results, i.e. sometimes the image upgrade works and most of the time it doesn't.

I have been using the following commands to sign and flash the image:
     rm -r build && west build -p auto -b nrf52840dk_nrf52840 samples/zephyr/hello-world/ -DCONFIG_BOOTLOADER_MCUBOOT=y -DDTC_OVERLAY_FILE="boards/nrf52840dk_nrf52840.overlay"
     west sign -t imgtool -- --key ~/zephyrproject/bootloader/mcuboot/root-rsa-2048.pem --header-size 0x200 --align 8 --version 3.0.2+1 --slot-size 0x67000 --pad && west flash --skip-rebuild -- --hex-file build/zephyr/zephyr.signed.hex

where the overlay file contains:
/ {
   chosen {
      zephyr,code-partition = &slot1_partition;
   };
};

I used --pad for both slots. I've noticed that sometimes when I flash to slot 1, sometimes the primary image swap_type=0x2 (test) and sometimes it's 0x4 (revert).
I have confirmed that I am flashing my slot0 and slot1 images to the correct addresses (with padding).

I am not sure if the Version number plays a role in my error. Do you have any suggestions on the top of your mind as to why I am getting sporadic results with the firmware upgrades?

With thanks

Re: MCUboot - Signing image for slot 1 #mcuboot

Martin Kozusky
 

Hi,
why do you want to compile it with offset of slot1? Normaly you compile image for slot0, upload it to slot1 and MCUboot will swap them after reboot.

Setting MAC address at boot? #stm32

Anders
 

Hi,

I'm new to Zephyr and is struggling with how to configure the MAC address for the ethernet interface on an STM32F767 based platform at boot.
I have searched the internet and the Zephyr documentation for guidance but have not found anything useful.

I have managed to set the MAC address at boot by modifying the function eth_initialize in eth_stm32_hal.c but there must be another way of doing this then modifying the driver or?

PlatformIO for flashing zephyr code on ESP 32

Komal Rajput-Hajare <komal.hajare5@...>
 

Hello Zephyr foundation

     Currently I am working on ESP32 and zephyr RTOS. But using PlatformIO IDE. My client want zephyr RTOS on ESP32 but only via platform IO. I got sucess using west tool. But not by PlatformIO ide. 

I didn't found any support from zephyr for PlatformIO specially for esp32. 

Do any one have idea about it? how can I do that? 

Can you please help me in this.


Thank you and Regards

Share variables between threads

Hi all,
is it possible to have some sort of global variables in Zephyr which can be shared between several threads? If yes, how can I create and access them?

Thanks for your help.

Cheers, Mike

Hi Robert,

thanks a lot for your answer! Increasing CONFIG_WEBSOCKET_MAX_CONTEXTS to 2 solved it:)
