SPI_Slave Example Code, print result messy (IDFGH-14238)

[Bennyggcc]

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.

IDF version.

V3.5.2

Espressif SoC revision.

ESP32-S3

Operating System used.

Windows

How did you build your project?

VS Code IDE

If you are using Windows, please specify command line type.

None

Development Kit.

Custom Board

Power Supply used.

USB

What is the expected behavior?

I run the SPI_Slave Example Code (esp-idf/examples/peripherals/spi_slave /(sender/receiver)), run 'sender code' on one esp32-s3 board as master, 'receiver code' on another esp32-s3 board as slaver.

master code revised the SPI pin as follow:

slave code revised the SPI pin as follow:

I hope the host/slave can send data correctly and receive the response from the slave/host.

But get error: --- Warning: Failed to decode multiple lines in a row. Try checking the baud rate and XTAL frequency setting in menuconfig. The XTAL frequency of ESP32-S3 just can be set as 40Mhz, and I try to set the baud rate to 115200 still get the error. How can I solve these problems?

Thank you!

What is the actual behavior?

But the print content is the messy code as follow:
Master print:

Slave print:

Steps to reproduce.

I just reproduce on SPI_slave example code, and change the correct SPI PIN, did not change other places.

Seems like slave can receive what master send, however master can not receive what slave send.

As you are using your Custom Board, can you check if any hardware issue, maybe on your GPIO12/13,

Or you can simply re-oder/change these pins and try again

@wanckl Thanks for your reply. But it seems not the hardware issue. I have succeeded to use this example code (https://github.com/hideakitai/ESP32DMASPI) based on the pins mentioned above to communicate between the Master and Slave device.
