Hello, i have a weird situation with the sd/mmc card recovery mode on my custom imx8mmini board.
When i don't burn the efuses for boot selection, it boots normally from the sdcard.
When i burn the fuses (to nand + bt_fuse_sel) it normally starts from nand
When i try to press the boot mode pin so that BOOT_MODE[1:0]=01b it's directly skipping the sdmmc card to usb downloader mode. This behaves the same, before and after burning the fuses. I am able to transfer a image via the uuu tool, so I am sure that it is in the usb dowload mode.
The Disable SDMMC Manufacture mode bit is set to 0 (didn't touch that one)
And while looking the graph i thought it should behave the same if it is boot_mode=0 + bt_fuse_sel=0 or when puting the boot_mode to 1
Do I maybe need to fuse something else? modify my u-boot spl code? Any ideas would be appreciated!
BT_FUSE_SEL is fused to 1
BOOT_MODE should be 1 when i press my button
My expecation is, when i press the BOOT_MODE to 1, that it behaves the same as when the BOOT_MODE = 0 + BT_FUSE_SEL = 0 but it doesn,t it jumps directly to usb download
