Hi all,
I am trying transition from SDK 15.0 to 17.2 and having a branch instruction to itself (an infinite loop) which I think has something to do with the adjustment of the Flash and RAM macros. Current development on a nrf52 DK but will transition to a 52810 chip with 192K Flash and 24K RAM. And using the s112 soft device.
With a 192K flash size, FLASH_PH_SIZE = 0x2EE00.
With a 24K RAM size, RAM_PH_SIZE = 0x5DC0.
When I debug through the program, I find RAM_START=0x20001AE0. This leaves RAM_SIZE=0x42E0 to satisfy (RAM_SIZE + RAM_START) should not be larger than (RAM_PH_START + RAM_PH_SIZE).
Due to the s112 softdevice, the FLASH_START=0x19000. This leaves FLASH_SIZE=0x15E00 as to satisfy FLASH_SIZE should not be larger than (FLASH_PH_SIZE - FLASH_START).
With these findings, this should be the correct macros but don't seem to work in SDK 17.2:
FLASH_PH_START=0x0
FLASH_PH_SIZE=0x2EE00
RAM_PH_START=0x20000000
RAM_PH_SIZE=0x5DC0
FLASH_START=0x19000
FLASH_SIZE=0x15E00
RAM_START=0x20001AE0
RAM_SIZE=0x42E0
Previous Macros in SDK 15.0 that worked for the same code.
FLASH_PH_START=0x0
FLASH_PH_SIZE=0x2EE00
RAM_PH_START=0x20000000
RAM_PH_SIZE=0x5DC0
FLASH_START=0x19000
FLASH_SIZE=0x15E00
RAM_START=0x20001b18
RAM_SIZE=0x42A8
Once all modules are initialized, and main() is entered, the code gets stuck in this infinite loop.
0x0001D808: b 0x0001D808 # while(main_state == OFF); where main_state is incremented on a push button which is verified to increment in debug.
There is enough memory for the application on this system and the code is the same as it is in the SDK 15.0 version. The .config file has been changed to enable the appropriate modules that were enabled in the 15.0 version.
Any thoughts would be appreciated
