I modified the MDD layer of RIL. After dialing, the GPRS module returned CONNECT. At this time, I returned RIL_NOTIFY_CONNECT in the MDD layer, which was wrong. What should be returned at this time? I...
Yesterday, when I was debugging stm32, a wrong rom table component id error suddenly appeared when I downloaded the program. The pop-up dialog box showed no cortex_m device found in jtag chain. I trie...
I'm working on serial communication between PC and PDA recently. Now the PDA can send data and the PC can receive it. However, the PDA cannot receive data when the PC sends data. The same program code...
