Hi, I'm trying to boot an A33 tablet , i buy sdcard breakout and enable sd card uart in .config using (UART0 on MicroSD breakout board).
I used q8_a33_tablet_1024x600_defconfig as base. I read serial port output from BOOT0 and finally "eraly jump fel" message so i'm sure sdcard breakout work. and from my linux 16.04 command line u-boot-2016.09# sunxi-fel -v ver AWUSBFEX soc=00001667(A33) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000 u-boot-2016.09# sunxi-fel -v uboot u-boot-sunxi-with-spl.bin Stack pointers: sp_irq=0x00002000, sp=0x00005E08 MMU is not enabled by BROM => Executing the SPL... done. libusb usb_bulk_send error -7 u-boot-2016.09# Nothing happen!! My tablet not boot direct from sdcard obviously(only installed android work), what can do for deeper debug ? I see that there is a early uart debug option in .config but ask parameters that i don't know.
