Hi Przemyslaw, I have a question.
"dfu_alt_bootloader" env is settings successfully > dfu_alt_bootloader=u-boot raw 0x3e 0x800 mmcpart 1 But, In order to replace bootloader binary in thor mode, How can I use the "dfu_alt_bootloader" env? DFU gadget use "dfu_alt_info" env for DFU entities configuration. Is there any patch to support multiple "dfu_alt" environment, or "dfu_alt_info" environment settings to use "dfu_alt_bootloader" env? best regards, Inha Song.
