MMWAVEICBOOST: My ICBOOST always fails to flash bin file via uniflash

This is my ICBOOST connected to IWR6843ISK. I set the SOP 1 0 1 for flash mode and I checked my UART port is com4 but I failed many times to flash bin file via uniflash. It said opening com for com4 and then the error occurred "[ERROR] Cortex_R4_0: Not able to connect to serial port. Recheck COM port selected and/or permissions.". I powered cycle and reset many times it still didn't work.

I just repowered the board many times and luckily, it worked one time, and then when I tried to flash another bin file it failed again.

请问每次尝试烧写时com口都能正常识别吗？

在其它电脑上再测试一下或者是否有相同的其它板子测试看看。
