I use custom board with CC2640R2F. I use CCS 10.2.0.00009 and SimpleLink CC2640R2 SDK 4.30.0.08. If I got any example from SDK I can build it properly. But if I try to debug the code using Segger J-link Base it fails during flashing with "Cortex_M3_0: Trouble Writing Memory Block at 0x1ffa8 on Page 0 of Length 0x58: Flash download failed! ...". If I use e.g. Uniflash to check the memory everything seems to be programmed until block 0x1ffa8. This block is CCFG, right? Why can't I program this block and run the HW?
