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 ...

I'm not using USB nor ADC/DAC on the STM32MP157A. Can I tie VDDA, OTG_VBUS, AND VDD3V3_USBxS to circuit ground (VSS)?

If I'm interpreting Table 13 correctly (datasheet p 128), VDDA can be set to 0 volts provided VREF is not used. Similarly power pins related to USB can also be set to 0 volts. Looking in the datasheet p29,I just need to star-connect VDD_ANA, VDD_PLL...

Resolved! The question about STM32MP157CAC3 supply

Hello. I have used the STM32MP157A-DK1 this year and I have learned to work with it. Now I develop my own PCB with STM32MP157CAC3. There is a 12-V external power supplier in it. I do't use USB Type-C. Can I do like this? I care about pins USB_PWR_CC1...
