Hi,
After selecting the AT port with the QFlash tool and flashing, the status and net_sta leds turns off. Then in the device manager panel, ports such as AT, AP, CP disappear and only the SPRD U2S Diag port remains. Since there is no AP port afterwards, I cannot watch the uart trial with coolwatcher. How can i fix this problem ? Thank you in advance for your help…
