Hi! I have tried to boot from an SD card into my Iris 2.0 board using both a tdx-reference-minimal-image I built and another I’ve got from Toradex’s site.
In both cases I’ve got:
U-Boot 2019.07-3.0.4+g26d926eda0 (Apr 17 2020 - 21:32:25 +0000) CPU: Freescale i.MX7D rev1.3 1000 MHz (running at 792 MHz) CPU: Extended Commercial temperature grade (-20C to 105C) at 32C Reset cause: POR DRAM: 512 MiB PMIC: RN5T567 LSIVER=0x01 OTPVER=0x0d NAND: 512 MiB MMC: FSL_SDHC: 0 Loading Environment from NAND... OK In: serial Out: serial Err: serial Model: Toradex Colibri iMX7 Dual 512MB V1.1D, Serial# 06786546 Net: FEC0 Hit any key to stop autoboot: 0 Colibri iMX7 # Colibri iMX7 # run sdboot Booting from MMC/SD card... 7035192 bytes read in 320 ms (21 MiB/s) Colibri iMX7 #
What could be going wrong here? I also tried with a USB mass storage device and could not find the image in it.
I confirm both the SD card and the USB mass device have two partitions with the correct formatting.
