Hello,
I am trying initialize an A40i board using USB OTG port when the device is in Fel mode. Pulled this board from an Arcade1up cabinet. sunxi-fel -l USB device 001:075 Allwinner R40 13000001:94404700:78928308:300f05d1 The Soc is labeled A40i with no visible writing on the Dram chip. I’ve tried to compile u-boot using defconfigs of the two available boards based on the R40(Banana Pi M2 Ultra and Berry). I’ve also tried several different memory settings “CONFIG_DRAM_CLK” including failsafe setting but the board appears to hang at DRAM initialization. sunxi-fel spl u-boot-sunxi-with-spl.bin *Serial Output * U-boot SPL 2020.04-rc3 DRAM: I attempted to follow the retrieving device information wiki but the read commands time out. sunxi-fel read 0x42400000 0x82d0 boot1.header usb_bulk_send() ERROR -7: Operation timed out No serial output is displayed during a normal boot. Any suggestions of how I can determine the memory setting for this board? Is the A40i Soc supported as a R40 device?
