Hello Peng, I tried following commands in order to load os bin file "loadb 0x80008000 ## Ready for binary (kermit) download to 0x80008000 at 115200 bps... ## Total Size = 0x00018fac = 102316 Bytes ## Start Addr = 0x80008000 => dcache off => icache off => dcache flush => icache flush => go 0x8000800" but it is showing following errors undefined instruction pc : [<00912a5c>] lr : [<9ff5882c>] reloc pc : [<e81bfa5c>] lr : [<8780582c>] sp : 9ef50d58 ip : e59ff018 fp : 9ef568b0 r10: 00000002 r9 : 9ef50eb8 r8 : 9ffa1d04 r7 : 9efd73a8 r6 : 6a0191a8 r5 : 00000002 r4 : 9efd73ac r3 : 80008abd r2 : 9efd73ac r1 : 9efd73ac r0 : 00000001 Flags: nZCv IRQs off FIQs off Mode SVC_32 Resetting CPU ... resetting ... I am using default u-boot for i.MUX6UL which is "u-boot-imx6ulevk_sd.imx". Do I need to rebuild u-boot after some rework? Kindly help, I am completely stuck over here, failed to find appropriate way to load RTOS from SD Card.
