Unable to get uboot console on LS1012A freedom board.

[kishanpatel78]

Hello,

I am not able to get uboot console on ls1012a freedom board.

Initially on this board RCW file was flashed using codewarrior tap . After than this board did not come up with u-boot console.

After that I setup yocto on ubuntu (14.04) host system and build binaries using bitbake fsl-image-full command. And flashed PBL file(0x0 offset) and u-boot (0x100000 offset) using codewarrior tap . But result is same. device did not come up with u-boot prompt.

Can anyone help to resolve this issue? Please let me know if I am missing anything.

Regards,

Kishan Patel

Hello,

I have gone through it. I am using SDK-V2.0-1703. There is no change in behavior after flashing prebuilt image.

I have used following command to flash binaries.

fl_write 0x0 PBL_0x33_0x05_800_250_1000_default.bin

fl_write 0x100000    u-boot-qspi-2016.09+fslgit-r0.bin

and reset board. But did not get any u-boot console.

After that i tried to full flash-image provided with SDK and write it from 0x0 location.

fl_write 0x0 QorIQ_SDK_V2.0_LS1012AFRDM_20170331_QSPI_Flash.bin

the result is same. did not get any u-boot console .

If you built RCW and u-Boot with bitbake, make sure you byte-swapped them before programming. Alternatively, use the most recent SDK pre-built u-Boot and RCW. Visit the link below to download SDK pre-built binaries:

Hello,

I also tried to swap bytes as you mentioned but did not work.

tclsh ./byte_swap.tcl u-boot-qspi-2016.09+fslgit-r0.bin swapped.bin 8
