I did not use the recording function. My colleague told me that there might be a problem with ES8388 recording. He used to the recording function on another platform and it also did not work.

@Erwan SZYMANSKI I added the print code in es8328_set_sysclk()The output is "es8328_set_sysclk==>clk_id:0, freq:4096000, dir:0".Seeing the output, I have a doubt about how this 4096000 is generated.Thank you for your reply.

RGB LCD does not display

ES8388 codec cannot get mclk

Re: Good afternoon! I'm trying to use TSC2046 based touchscreen device on a STM32MP157C-DK2 based custom board. I get SPI transfer time-out when touching the screen. Does anyone have a similar problem ?
