I'm using iMX7D sabresd reference board.
When BOOT_MODE is 00b (SW2-00) board booting from SD card because eFuse boot configuration were already written so ROM code fetching boot loader from SD card.
I just want to read the efuse boot configuration from the board, so i tried in following way.
1. ==> fuse read 0x01 0x03 and the result is 0x0 same result for bank2,word0(BOOT_CFG1) and BOOT_CFG2, 3 and 4.
2. Then i tried from linux.
cat /sys/fsl_otp/HW_OCOTP_BOOT_CFG0 result is 0x0 and same for BOOT_CFG1,2,3 and 4.
How to read the efuse boot configuration data?
