I am using tirtos_simplelink_2_11_01_09 and 5x5 silicon. After I reconfigured to build for CC2650EM_5XD and run my firmware which uses UART. I found that is always hung somewhere before even the main() is called. When you pause the execution (I am using CCS), I see in stuck on ti_sysbios_hal_HwiProxy_Object__delete__S__mangled__().
After chasing down the code, I found this line in UART.c cause the problem:
...
handle = (UART_Handle)&(UART_config[index]);
...
Further scratching the head, I found this abnormality in ~/CC2650EM_5XD/board.c:
... #pragma DATA_SECTION(uartCC26XXObjects, ".const:uartCC26XXObjects") ...
comparing to ~/CC2650EM_7ID/board.c and ~/CC2650EM_4XS/board.c::
... #pragma DATA_SECTION(uartCC26XXHWAttrs, ".const:uartCC26XXHWAttrs") ...
After I make the change in ~/CC2650EM_5XD/board.c to be the same as in ~/CC2650EM_4XS/board.c and ~/CC2650EM_7ID/board.c, the problem goes away.
Please confirm that it is a bug, and more particularly, the change mentioned in the correct fix.
