Member: 13148 Status: Offline Thanks Meter: 2,948 | Try set 1,8 IO You need set HiPower CLK mode only with power device from USB (not 1,8/2,8 from box) also you can add pull-up resistors 100-200 ohm for D0/CMD lines |

Member: 13148 Status: Offline Thanks Meter: 2,948 | Mediatek CPU can connect only via HiPower CLK mode (power from USB, not use 1,8/2,8 lines) Also at ISP connection You Need use TOLD GND wire For some devices you can add 15-20 ohm resistor to CLK line Last edited by layder; 07-27-2020 at 08:34. |
