Answers checklist.

• I have read the component documentation ESP-IDF Components and the issue is not addressed there.
• I am using target and esp-idf version as defined in component's idf_component.yml

ESP-IDF version.

5.0.4

Development Kit.

Custom board

Used Component version.

More Information.

First of all thank you for this very useful extension for me.
I use a W25N01GVZEIG flash which works very well on its own.
But I also use a w5500 ethernet spi module on the same spi bus. The two together don't work. After some research I think I found the problem. In the "spi_nand_execute_transaction" function I replaced "spi_device_transmit" by "spi_device_polling_transmit" and everything works now.

BTW : I can't compile espressif/spi_nand_flash 0.1.0 I always get "dhara/map.h" not found

@RathiSonika could you please take a look?

Hello @Coco1780 , Thank you for bringing up the issue. I'll investigate the spi_nand_execute_transaction function.

Regarding the compilation problem, the spi_nand_flash component relies on the dhara library, which is included as a separate component in the component repository. If you're compiling the example within the idf_extra_components repository, please initialize the submodule using the command git submodule update --init dhara/dhara, and then try again. Alternatively, you can remove the override path from the example's idf_component.yml file and attempt to compile it again. This should resolve the issue.

Hello @Coco1780,
I’ve tested the W5500 Ethernet module along with an SPI NAND flash on the same SPI bus using ESP32, and everything appears to be working fine. I used the example available in esp-idf/examples/ethernet/iperf and integrated it with the spi_nand_flash driver. During testing with iperf for Ethernet performance and simultaneous NAND flash access, I didn’t observe any issues using the attached patch.

ethernet_nand_flash.patch

Have you already managed to solve the issue? If not, please take a look at the patch and let me know if it helps.

Hello @RathiSonika ,

I fixed the issue by replacing "spi_device_transmit" with "spi_device_polling_transmit" but haven't made any further changes since.
Since then, we have replaced the NAND with an SD card for more stability and more storage space.

If I find some time I will test the patch. A lot has changed since then (esp-idf 5.0.4, spi_nand_flash 0.1.0)

Thx a lot.
