I have a iMX6S with 256Mb of ram and an eMMC of 4Gb.
I know that iMX6 processor has two pins (BOOT_MODE[0:1]) which are related to the recovery mode, and those (whenin short-circuit)put the processor in Serial Downloader mode.
My question is related to the flash process of a "out of production" iMX6 processor. Iniatially, it’s necessary to blow eFuses. Can you tell me how this process is done? You configure BOOT_CFG1[7:4] as 011x, right?
Relatively to the flash process itself, what are the possible processes to flash everything (bootloader, rootfs, kernel) in the eMMC? I know I can flash the bootloader through Serial Downloader mode, and then use the bootloader to flash the kernel + rootfs to the eMMc, but is there a way to flash them all at sequentially? Without the need to stop at the bootloader?
