TDA2PXEVM: Lzop decompression fails when loading firmware from qspi

Padmesh K Gopi

Part Number: TDA2PXEVM

Hi team,

I am working on early boot usecase of vision SDK v3.07

I have managed to flash the lzop compressed IPU2 firmware to qspi and is now able to load the firmware from qspi by the MLO.

The debug log shows the loading of the firmware is successful from qspi to RAM, but the lzop decompression fails and is not able load the firmware properly.

The lzop firmwares generated during the linux build is applied with mkimage signature as follows mkimage -d dra7-ipu2-fw.lzop > dra7-ipu2-fw.uImage

The dra7-ipu2-fw.uImage is then flashed to qspi.

What might be going wrong here ? Could you help me find out this issue, as I have been struggling to get this for a while.

Regards,

Padmesh

Hi,

Are you flashing the image from the target or host?

Thanks

Hi,

I don't have QSPI flash setup right now & the cable used for QSPI is not detecting in setup. So I will try to resolve the issues asap & I will come with solution for this issue.

Thanks

Hi,

Can you try with "dra7-ipu2-fw.xem4" images instead of "dra7-ipu2-fw.lzop"?

Thanks

Hi,

I tried the same, but still it reads the firmware to RAM, but again goes to do decompression for xem4 which shouldnt happen.

Hi,

Please follow the below steps to flash all images to QSPI memory

mmc dev 0

sf probe 0

fatload mmc 0 0x82000000 qspi/MLO

sf erase 0 0x20000

sf write 0x82000000 0x0 0x20000

fatload mmc 0 0x83000000 qspi/uImage

sf erase 1e0000 0x800000

sf write 83000000 1e0000 0x800000

fatload mmc 0 0x82000000 qspi/dra76-evm-infoadas.dtb

sf erase 140000 0x80000;

sf write 0x82000000 0x140000 0x80000

fatload mmc 0 0x83000000 qspi/dra7-ipu2-fw.uImage

sf erase E60000 0x400000

sf write 83000000 E60000 0x400000





Repeat the step to flash other core firmware to the QSPI memory. Flashing memory address & len is given in the below table.

Core	Offset	Len
IPU1	A60000	0x400000
DSP1	1260000	0x400000
DSP2	1660000	0x400000














Use the below command to wrapping the binaries in uImage header using mkimage

mkimage -d $LINUX_TARGETFS/lib/firmware/dra7-ipu2-fw.lzop dra7-ipu2-fw.uImage

Thank You Gaviraju,

But I see this issue on loading the ipu2 firmware,

Hi,

spl: loading remote core image dra7-ipu2-fw.lzop

mkimage signature not found

According to the above log still, you are flashing the ".lzop" image instead of ".uImage"

Please use the below command to flash firmware to the QSPI.

fatload mmc 0 0x83000000 qspi/dra7-ipu2-fw.uImage

sf erase E60000 0x400000

sf write 83000000 E60000 0x400000


Use the below command to convert from .lzop to .uImage & this command should run from the host then copy the dra7-ipu2-fw.uImage into SD card

mkimage -d $LINUX_TARGETFS/lib/firmware/dra7-ipu2-fw.lzop dra7-ipu2-fw.uImage


Note: The above steps we alredy validated in our set-up & it's working fine.


Thanks
Gaviraju

Tge -d $LINUX_TARGETFS/lib/firmware/dra7-ipu2-fw.lzop dra7-ipu2-fw.uImage
