LS1012A-FRDM : Error when flashing the PPA Image

anais_battut — Fri, 07 Aug 2020 15:03:57 GMT

Hi,

I have got a problem when I try to flash the PPA image on the LS1012A-FRDM. Indeed, according to the "QorIQ FRDM-LS1012A board Getting Started ", to update FRDM-LS1012A board image, and in particular the PPA image (ppa.itb), you need to follow the instructions :

=> tftp 0x96000000 ppa.itb
Speed detected 3e8
Using pfe_eth0 device
TFTP from server 192.168.1.1; our IP address is 192.168.1.3

device 0 offset 0x500000, size 0x15bc3
SF: 89027 bytes @ 0x500000 Written: OK

I have flashed the Kernel Image with success, but when it comes to the PPA image, an error comes up when I reboot the board :

fsl-ppa: Bad firmware image (not a FIT image)
fsl-ppa: error (-22)

The PPA image is from : Linux® SDK for QorIQ® Processors | NXP

When I look into the adress where the PPA Image is flashed, I am expecting to see :

=> md.w 0x40500000

However, on the board that I just flashed with the new version of the PPA image :

I don't understand the problem and don't know how the PPA image ended up reversed. I followed the tutoriel on "NGS-FRDM-LS1012A : Get Started with the FRDM-LS1012A"

Thank you.

It seems that PPA firmware on the target board should be as the following.

After executing "sf write 0x96000000 0x500000 $filesize", please check whether "md.w 0x96000000" and "md.w 0x40500000" get the same result.

When I check for "md.w 0x96000000" and "md.w 0x40500000", I get the same result but reversed and I am not sure why...

For "md.w 0x96000000" :

Please execute the following command to do byte swapping, then program ppa.itb_swap to the target board.

$ tclsh byte_swap.tcl ppa.itb ppa.itb_swap 8
