The 'boot.scr' script here is board/solidrun/mx6cubox/boot.scr.txt from the Buildroot repo: setenv finduuid "part uuid mmc 0:1 uuid" run finduuid run findfdt setenv bootargs "console=ttymxc0,115200 root=PARTUUID=${uuid} rootwait rootfstype=ext4" load mmc 0:1 ${fdt_addr} boot/${fdtfile} load mmc 0:1 ${loadaddr} boot/zImage bootz ${loadaddr} - ${fdt_addr} Is that correct? > Now, with the version 2020.07 > > U-Boot SPL 2020.07 (Oct 06 2020 - 13:33:44 +0200) > WDT: Not found! > Trying to boot from MMC1 > > > U-Boot 2020.07 (Oct 06 2020 - 13:33:44 +0200) > > CPU: Freescale i.MX6SOLO rev1.3 996 MHz (running at 792 MHz) > CPU: Commercial temperature grade (0C to 95C) at 36C > Reset cause: POR > Board: MX6 Cubox-i > DRAM: 512 MiB > MMC: FSL_SDHC: 1, FSL_SDHC: 2 > Loading Environment from MMC... *** Warning - bad CRC, using default > environment > > No panel detected: default to HDMI > Display: HDMI (1024x768) > In: serial > Out: serial > Err: serial > Net: > Warning: ethernet@2188000 using MAC address from ROM > eth0: ethernet@2188000 > Hit any key to stop autoboot: 0 > switch to partitions #0, OK > mmc1 is current device > Scanning mmc 1:1... This might be the cause of the problem. The script listed above hardcodes "mmc 0:1". Changing that to "mmc 1:1" might fix this issue. baruch > Found U-Boot script /boot/boot.scr > 336 bytes read in 12 ms (27.3 KiB/s) > ## Executing script at 12000000 > SCRIPT FAILED: continuing... > switch to partitions #0, OK > mmc2(part 0) is current device > ** No partition table - mmc 2 ** > No SATA device found! > starting USB... -- ~. .~ Tk Open Systems =}------------------------------------------------ooO--U--Ooo------------{= - bar...@tkos.co.il - tel: +972.52.368.4656, http://www.tkos.co.il -
