err_code=NRF_ERROR_INVALID_PARAM at SOFTDEVICE_HANDLER_INIT() function

[AnthonyThet]

Hi all, I found one issue with my custom nrf51422ble board. When I use my office PC and KEIL IDE, my custom board BLE is working but when I use my home PC KEIL, it's not working. When I tried to debug, I found out that the code stucked in SOFTDEVICE_HANDLER_INIT and the err_code is 0x07 (NRF_ERROR_INVALID_PARAM). But it's very strange when I flash the same code from my office PC. Please can anyone help?

Hi,

Make sure that you have programmed identical softdevice binary, and that the entire project is the same (e.g. source and header files) and compiler version.

You can always read out the entire flash content by calling "nrfjprog --readcode dump_1.hex" and compare the hex files to make sure they are identical. You can program it to the second board by calling "nrfjprog --program dump_1.hex".

Best regards,
Kenneth

Hi Kenneth,

sorry for my late reply. Actually I checked that the softdevice version is the same and all other (source and header files) are same but when I readcode the flash and check the hex file, I found they are not identical. 

What should be the reason?

Do your application support bonding or write any data to flash? If yes, then part of the hex file may differ.

Hi Kenneth,

actually, my application doesn't support Bonding

Can you share your two hex files so I may take a look?
