Resolved! Can't boot STM32MP1 custom board because of PANIC at PC : 0x2ffdaa77
Hi,I'm trying to bring up a custom board based on STM32MP151C MPU. The design is widely taken from the devkit.I'm booting from SDCARD and bootpins are set accordingly (b101).One thing that is changing is the I2C4 pins for PMIC interface (still on I2C...
What is the machine type constant to be used for booting Linux in STM32MP1 (STM32MP157F-EV1)?
Hello, I am working on a custom Boot Loader (SSBL) for the STM32MP157F-EV1 board to replace U-Boot in the boot chain (BL33), this is a requirement for my project. As I understand, to boot the Linux Kernel it is needed to provide 3 values through ...
Resolved! TF-A failing at fsbl1 to BL2 transition. What could be causing it?
Hello, I am currently working on bringing up a production board design with the OSD32MP157C-512M-BAA. The board design is very similar to the octavo systems osd32mp1-red boardSdcard is located on SDMMC1 with the same pinout.EMMC is located on SDMMC2 ...
Can we swap SDMMC pins in our design ?
Does ST-Linux run for any configuration of eMMC pins, i.e. if it is connected to SDMMC1/SDMMC2/SDMMC3 . or do we need to fix as per reference design / Dev kits.
