Resolved! Hello, i'd like to use u-boot command sspi to send commands to a spi device with a custom protocol (not a memory). However I see that the command tries to read an ID as it is talking to a flash nor : unrecognized JEDEC id bytes: 00, 00, 00.

Looking at the code, i see file sf_probe.c with .id      = UCLASS_SPI_FLASH, that performs the id reading. How can i use stm32_spi.c with .id         = UCLASS_SPI, driver instead? and send "raw" spi data?

Resolved! Hello, I've exported our custom root filesystem from a running board with the following command: dd if=/dev/mmcblk1p4 of=/usr/local/rtfs.ext4 bs=1M conv=fdatasync

I noticed that after I flash the ST starter package root filesystem, at first boot there is a check on bad blocks and a resize of the partitions, while when I flash the exported root filesystem, there is no checks and some partitions are not resized ...
