Sloth Posted October 24, 2022 Share Posted October 24, 2022 By pure accident, I discovered that Ctrl-Alt-F1 while the P2 is booting brings up more options on mine that allows the deletion of firmware and clearing of emmc. I have not done it but the menus are there. 0 Quote Link to comment Share on other sites More sharing options...
CryBaby Posted October 25, 2022 Share Posted October 25, 2022 I have tried the clearing of eMMC option. Unsurprisingly it cleared the eMMC and I can no longer boot to Station OS. I can still boot to Balbes' UPDATE_UBOOT image from SD card. The other option is 'Delete bootloader'. I have not tried this but I think it must clear the SPI. You would definitely want a working uboot in eMMC before doing that. The question I have is if you do that and have an empty SPI will the bootrom go to the eMMC or will it hang? Firefly have RK356x_NorFlash2eMMCLoader_20211209.img which suggests you need something in SPI (aka NorFlash) to redirect to the eMMC. This page goes into it. I don't have Windows, no longer have Station OS (so no ADB) and have so far failed to enter MaskROM mode so I'm a bit stuck. 0 Quote Link to comment Share on other sites More sharing options...

If you clear SPI and eMMC, the bootloader from the SD card should work. By the way, if you completely remove u-boot from SPI and eMMC, you can use two bootloader options to run from an SD card (and later install on eMMC) - the old 2017 or the new 2022. Important - The new u-boot-2022 is not compatible with StationOS, i.e. you will not be able to use it with Android (StationOS) 0 Quote Link to comment Share on other sites More sharing options...
