error parameter in spi_bus_initialize when using example connect (IDFGH-9750)

[gl-chenxiaosheng]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

IDF Version: master(ab63aaa)

I use esp32s3 and eth module DM9051 to run example ot_br.
And it couldn't work as expect, log as follow:

I (571) app_start: Starting scheduler on CPU0

I (575) app_start: Starting scheduler on CPU1

I (575) main_task: Started on CPU0

I (585) main_task: Calling app_main()

E (605) spi: spi_bus_initialize(774): invalid dma channel, chip only support spi dma channel auto-alloc

ESP_ERROR_CHECK failed: esp_err_t 0x102 (ESP_ERR_INVALID_ARG) at 0x4200afc7

0x4200afc7: eth_start at /home/kelly/esp/esp-idf/examples/common_components/protocol_examples_common/eth_connect.c:125 (discriminator 1)



file: "/IDF/examples/common_components/protocol_examples_common/eth_connect.c" line 125

func: eth_start

expression: spi_bus_initialize(CONFIG_EXAMPLE_ETH_SPI_HOST, &buscfg, 1)



abort() was called at PC 0x4037f207 on core 0

So I modify the param in spi_bus_initialize, it work.
I hope this configuration can be fix and merge into the branch, thanks.

OK, I will confirm the problem and fix it.

Hi, I have the same problem with an esp32-s3 and a wiznet w5500.

I (44) boot: ESP-IDF v5.1-dev-4167-gab63aaa4a2 2nd stage bootloader
I (45) boot: compile time Apr 18 2023 10:51:48

E (1674) spi: spi_bus_initialize(764): invalid dma channel, chip only support spi dma channel auto-alloc ESP_ERROR_CHECK failed: esp_err_t 0x102 (ESP_ERR_INVALID_ARG) at 0x4200f4be 0x4200f4be: eth_start at /home/jjsch/esp/esp-idf/examples/common_components/protocol_examples_common/eth_connect.c:125 (discriminator 1)

I also fixed the problem by changing the code of the function eth_start in the eth_connect.c file.

Fail
ESP_ERROR_CHECK(spi_bus_initialize(CONFIG_EXAMPLE_ETH_SPI_HOST, &buscfg, 1));

Success
ESP_ERROR_CHECK(spi_bus_initialize(CONFIG_EXAMPLE_ETH_SPI_HOST, &buscfg, SPI_DMA_CH_AUTO));

@xieqinan ETA on this?

[xieqinan]

The error has already been fixed, and it will be synced to esp-idf today or tomorrow.

[jjsch-dev]

@xieqinan thanks for reply, when you make the change in the master, I update the IDF and compile my project to confirm that the problem is fixed.

[jjsch-dev]

@xieqinan I did the pull to the master and tried it with my motherboard that has a PHY W5500 and it works fine, thank you very much for the work.

[xieqinan]

@jjsch-dev Happy to help you.
