I managed to set U-boot output to UART1, the reason was that I tried to program u-boot image to default rk3308 cfg address 0x4000 in RKDEVTool. After I changed it to 0x2000, all worked well.
Next step for me to connect to U-boot with JTAG (SWJ), seems like some peripheral re-init those pins, cause connection to cpu not working in u-boot unlike MaskRom, to which I can connect with OpenOCD. Anyway, work continues |
