[PATCH] config: imx: Add support for Phytec's phycore imx8mm running SDP gadget
After this change it would be possible to boot SDP gadget when Phytec's Phycore imx8mm module has USB ROM boot selected.
With this change it shall be possible to flash eMMC/SD card content with uuu program.

With these changes booting via SDP with uuu and flashing emmc with uuu should work. Sadly I did not find a way to be able to flash eMMC and SD-Card over uuu with the same bootloader because it was necessary for me to specify the device to flash in CONFIG_FASTBOOT_FLASH_MMC_DEV.
with kind regards, Benjamin

QSPI is flashed via USB - however - I've noticed that there are some flipped bits on USB transmission when I do compare it with tftp transfer.
This needs to be investigated, however seems to be an orthogonal problem from QSPI boot support.

I tested your branch. Your commands seem to work. Here is the log:

Booting over qspi does not work. Probably because it is not a dedicated qspi flash image (does not get flashed with the correct offset).
About some bits getting flipped: For me it is not just some bits getting flipped. I read back the image from /dev/mtd0 with the dd command and compare the hexdump ouput to the original image. Theoretically it should identical, but that is not the case. There are not just some flipped bits, but the Image flashed via uuu looks like a completely different image. I also tested flashing with dd in linux and in U-Boot with loading the image via fatload from the sdcard and flashing it with "sf update ${loadaddr} 0 ${filesize}". With those two flashing methods I get an Image that is identical to the original Image when I read it back, as I would expect.

With these changes booting via SDP with uuu and flashing emmc with uuu should work. Sadly I did not find a way to be able to flash eMMC and SD-Card over uuu with the same bootloader because it was necessary for me to specify the device to flash in CONFIG_FASTBOOT_FLASH_MMC_DEV.

Booting over qspi does not work. Probably because it is not a dedicated qspi flash image (does not get flashed with the correct offset).
Are you using imx8mm or imx8mn ?

About some bits getting flipped: For me it is not just some bits getting flipped. I read back the image from /dev/mtd0 with the dd command and compare the hexdump ouput to the original image. Theoretically it should identical, but that is not the case. There are not just some flipped bits, but the Image flashed via uuu looks like a completely different image.
Ok - strange...
Then uuu (and USB) needs to be debugged.
I also tested flashing with dd in linux and in U-Boot with loading the image via fatload from the sdcard and flashing it with "sf update ${loadaddr} 0 ${filesize}". With those two flashing methods I get an Image that is identical to the original Image when I read it back, as I would expect.
Ok.
Just to be 100% sure - are you able to boot from QSPI with the flash.bin build from https://github.com/lmajewski/u-boot/commits/phycore-imx8mm-qspi-nvme

To me it looks like there are some changes missing to get this feature to work. You can take a look at my commits where I added this feature for imx8mp. 199229e28b2b2da57c52ee46452f930785cf6002 ("phycore-imx8mp: add USB mass storage support") 8dcf1df48dff339b172d1bce2a38a965ee4aafca ("phycore-imx8mp: add support for booting and flashing emmc via UUU")

I used the branch you sent me to build the flash.bin binary. And yes this commit is included in your branch.

Yes, tested it with these commands. I get the same result as when I load it from the sdcard (identical image is read back from the qspi flash after flashing).

No. Does not work for me. When I reset after flashing and set the boot switches to qspi flash boot, nothing comes up. The Image boots fine from sdcard though when flashed with the correct offset (33k).
To me it looks like there is no offset in the image and I see that we flash the image to the beginning of the qspi flash => so offset 0x0. Is there also some offset that needs to be set for qspi flash?
Is there somthing specific that I need to build? I just did "make flash.bin" like usual to build the image.

To me it looks like there are some changes missing to get this feature to work. You can take a look at my commits where I added this feature for imx8mp. 199229e28b2b2da57c52ee46452f930785cf6002 ("phycore-imx8mp: add USB mass storage support") 8dcf1df48dff339b172d1bce2a38a965ee4aafca ("phycore-imx8mp: add support for booting and flashing emmc via UUU")
Here are the changes I needed to do on top of your patch to get this feature to work for mini:

With these changes booting via SDP with uuu and flashing emmc with uuu should work. Sadly I did not find a way to be able to flash eMMC and SD-Card over uuu with the same bootloader because it was necessary for me to specify the device to flash in CONFIG_FASTBOOT_FLASH_MMC_DEV.
with kind regards, Benjamin

After this change it would be possible to boot SDP gadget when Phytec's Phycore imx8mm module has USB ROM boot selected.
With this change it shall be possible to flash eMMC/SD card content with uuu program.
