How to modify nrf52820 DFU to nrf52833?

[JerryLin]

Hi,

I use DFU secure_bootloader pca10100e_usb example to modify to nrf52833 DFU.

But when I execute, I get stuck in this line, as shown below.

In configuration, I already change device to "nrf52833_xxAA", IROM start address 0x74000, size 0xA000, IRAM1 start address 0x20000008, size 0x17FF8.

Preprocessor define "BOARD_PCA10100 FLOAT_ABI_HARD MBR_PRESENT NRF52833_XXAA NRF_DFU_SETTINGS_VERSION=2 SVC_INTERFACE_CALL_AS_NORMAL_FUNCTION __HEAP_SIZE=0 uECC_ENABLE_VLI_API=0 uECC_OPTIMIZATION_LEVEL=3 uECC_SQUARE_FUNC=0 uECC_SUPPORT_COMPRESSED_POINT=0 uECC_VLI_NATIVE_LITTLE_ENDIAN=1" .

Is there an error in this process or anything else that needs to be modified?

Best Regards

Hi

I have notified the SDK team that there is no pca10100_usb example, and it will hopefully find its way into a future release of the SDK. It should not be too difficult to edit the project to run on the nRF52833 instead of the emulated nRF52820 hardware. You can follow the Developing for nRF52820 guide on the Infocenter and make sure you revert every step in the Hardware emulation of nRF52820 section, as that should be all the changes that are done to that project.

Best regards,

Simon
