Other Parts Discussed in Thread: LAUNCHXL-CC2640R2,
I designed a board with CC2640R2F based on LAUNCHXL-CC2640R2. When the PCB was finished, I began to write the program. There was no problem at the first time. The Bluetooth connection and the voltage was fine.However, when I used XDS110 to debug or to problem for many times, it suddenly failed. I use XDS110 in the CCS "test connection" to test it, it can work corrently, the working voltage is corrent, VDDR is the working voltage is 1.68V, PIN23 voltage is 1.26V, the voltage seems to have no problem, but when using CCS to write the program, it can not be downloaded.
it prompt Cortex_M3_0: Error connecting to the target: (Error -2062 @ 0x0) or Cortex_M3_0: Error connecting to the target: (Error -1170 @ 0x0).
I found that it can work correct when console print Cortex_M3_0: GEL Output: Memory Map Initialization Complete.But it only print Cortex_M3_0: GEL Output: Memory Map Initialization Complete and unreached the step Cortex_M3_0: GEL Output: Board Reset Complete.So I think the kernel of M3 can not be reset. Why did I work normally at the first time, and suddenly it wasn't.My several chips have the same problem.I using simplelink_cc2640r2_sdk_1_40_00_45 to develop.this is my sch.Is any problem in it?CC2640R2F_PER.pdf
