Hi,
1. I have my own application (migrated from H7 to N6) with FileX writing to the SD card in real-time.
And I see that 4-bit data bus is unusable at all (a lot of disk errors).
The 1-bit data bus in NORMAL mode works sometimes. HIGH-SPEED is not working properly.
The same data throughput was recorded on STM32H747I-DISCO perfectly via 4-bit bus.
Could you please advise on this?
2. Looking at STM32CubeN6\Projects\STM32N6570-DK\Applications\FileX\Fx_MultiAccess example,
I see that 1-bit data bus in Normal mode is used.
Is there any issue with the SDMMC on STM32N6 chip or STM32N6570-DK board (signal integrity)?
Regards,
A
