@rsglobal what's the deal with RPi4 ? they use hybrid GPT+MBR and can add an offset to GPT ?
@rsglobal OK, thanks for the precisions. I need to spy the sdcard signals to be sure the new SoCs don't look at other adresses. For eMMC, the Amlogic SoCs doesn't...
@rsglobal I did spy the SDCard signals and it reads LBA0x1 to LBA0x80 whatever the status of the bootloader (doesn't read anywhere else if the boot binary is invalid at...
Yep sure, I added some tweaks, linux needs no change except the "gpt" kernel param, U-Boot would need some change to only write the backup GPT.
@rsglobal here you go: - U-boot: https://github.com/superna9999/u-boot/commit/2dc9e4b6fa134403571fb7c478b578ee2ae90d95 - Linux https://github.com/superna9999/linux/commit/de90dda65748b7d58ab5ac2683fb1095f9620484 This one would require passing `alternate-gpt-okay` on the kernel cmdline
I've added an initial implementation in #16
I have no idea if GXBB implements this protocol, so far I have no plan to support this generation of SoCs in pyamlboot. But I'm open to contributions if you...

@dsx724 can you try https://github.com/superna9999/aml-usb-load-uboot/commit/dace10064ad8a9c74df6ae0580c12f54da49d890 ?
@m-kurbanov Hi sorry for the delay, the code looks real good and I don't have any comments so far, except about Documentation. Could you write some documentation on the protocols...
