Hi all, I have an PCA10001 board and a custom PCB which also uses the QFAA version (256KB flash, 16KB RAM). I'm trying to enable OTA feature for our custom board. I use the dual_bank_ble_s130 sample code (SDK8.0) with some modification to the linker script as below:
MEMORY { /** Flash start address for the bootloader. This setting will also be stored in UICR to allow the
- MBR to init the bootloader when starting the system. This value must correspond to
- BOOTLOADER_REGION_START found in dfu_types.h. The system is prevented from starting up if
- those values do not match. The check is performed in main.c, see
- APP_ERROR_CHECK_BOOL(*((uint32_t *)NRF_UICR_BOOT_START_ADDRESS) == BOOTLOADER_REGION_START); */ FLASH (rx) : ORIGIN = 0x3C000, LENGTH = 0x3C00
/** RAM Region for bootloader. This setting is suitable when used with s110, s120, s130, s310. / / RAM (rwx) : ORIGIN = 0x20002c00, LENGTH = 0x5380 */ RAM (rwx) : ORIGIN = 0x20002000, LENGTH = 0x1f80
/** Location of non initialized RAM. Non initialized RAM is used for exchanging bond information
- from application to bootloader when using buttonluss DFU OTA. */ NOINIT (rwx) : ORIGIN = 0x20003f80, LENGTH = 0x80
I also change the LED display and BUTTON number used in the bootloader code (PCA10001 only has 2 LEDs and 2 buttons as compared to PCA10028). So the code compiles just fine using gcc toolchain. I downloaded the hex file and softdevice using openocd and jlink. At this point, i haven't downloaded any application code. The device is not advertising any DFU service at all. So i tried to use my Jlink debugger to debug the code. It can run to main() in bootloader code, turn on the LED in my board, but then it doesn't do anything. Hope you guys can help me figure this out.
