Hello list! Thank you for let me adding to this Mailing List!
I am designing a custom board with a STM32MP157 (as the Evaluation Board), but without any USB nor microSD connectors.
My concerns are about to load FSBL and SSBL from USB (with a sort of extension cable from PCB to PC into a USB Host A Port) with Linux.
(A) My goal is to write u-Boot into the internal eMMC Flash Storage (via USB Recovery mode) and let u-boot continue the loading of the kernel (TFTPBoot) and the rootfilesystem via ethernet (NFS).
Is it a viable solution to you guys?
(B) I would like to avoid using an extension cable for microSD/SD card, due to the high speed involved in this.
The only drawback with (A) is I need a PC for every board to be programmed. Which tool is expected to work? STM32CubeProgrammer?
With (B) option every board does not need anything because u-boot can be written in internal eMMC within u-boot itself...
Or, are there any other option to write the internal flash?
What do you use guys?
