Cannot flash b_l4s5i_iot01a samples/hello_world #54614

Closed jvermillard closed 1 year ago

jvermillard commented 1 year ago

Describe the bug Just getting started with zephyr of this target, I try to follow the doc here: https://docs.zephyrproject.org/latest/boards/arm/b_l4s5i_iot01a/doc/index.html

I can compile, run west flash but my board is still running the previous firmware

To Reproduce

west build -b b_l4s5i_iot01a samples/hello_world
west flash

output:

Expected behavior The board running hello world and seeing the default message on the console

Environment (please complete the following information):

jvermillard commented 1 year ago

Forgot some details. Even after resetting the board, I don't have any other message on the UART console than:

STM32L4XX Lib:
> CMSIS Device Version: 1.7.0.0.
> HAL Driver Version: 1.12.0.0.
> BSP Driver Version: 1.0.0.0.
ES-WIFI Firmware:
> Product Name: Inventek eS-WiFi
> Product ID: ISM43362-M3G-L44-SPI
> Firmware Version: C3.5.2.5.STM
> API Version: v3.5.2
ES-WIFI MAC Address: C4:7F:51:94:4A:52
!!!ERROR: ES-WIFI NOT connected.
dns_create fail: 67

Which, I believe, is generated by the old firmware

There are some errors, this isn't a walk in the park, but it eventually succeeds.

Hello World! b_l4s5i_iot01a

Also, on your side, according to the log, it looks like it actually succeeds:

Looks actually odd that console output isn't matching.

erwango commented 1 year ago

One suggestion would be to update ST-Link version.

For unknown reason, I was not using latest SDK. Here is the log with SDK-0.15.2, using exact same version for openocd:

Also I upgraded my stlink using the IDE: image

still the same issue, west flash logs:

BTW my jumper configuration:

Looks ok.

Did you try to fully erase flash using STM32CubeProgrammer ? You can even try to flash using STM32CubeProgrammer:

board_runner_args(stm32cubeprogrammer "--port=swd" "--reset-mode=hw")

include(${ZEPHYR_BASE}/boards/common/stm32cubeprogrammer.board.cmake)

This should be put before:

include(${ZEPHYR_BASE}/boards/common/openocd.board.cmake)

I erased the flash using stm32cbueide and:

Hello World! b_l4s5i_iot01a

:tada: thanks for the help

kartben commented 1 year ago

That's an interesting one. As I'm assuming others might be bitten by it too, it might be worth updating the doc? And I guess it might be happening with other devkits?

Actually, it's rather unusual. But yes it would potentially apply to most ST STM32 platforms. This being said, rather than documenting it in each board documentation, what would be great is to have a kind of vendor doc section, in which we can centralize this kind of generic topic (and redirect from boards docs). We've discussed this, but never made it happen, this would be more than welcome ;-)
