DA14586 on-board firmware update via host mcu

Hi,

I want to realize an on-board firmware update function for the 14586 from host mcu via direct access to SPI. Can I use the addresses in the hex files created from Keil direct without any modifications to write progamm data to flash or do I have to make some address translations?

Thanks and regards,
Oliver

I believe you have to add a

I believe you have to add a header to the hex file so that DA14586 can boot from SPI flash at least.

我不确定about the detailed derivation but you can check mkimage tool under the utilities folder of SDK to get a picture of what has be done to prepare a hex file into bootable image.

Thanks, that points me to a (perhaps) much better solution:

  1. I convert my hex file to a binary file with hex2bin.exe
  2. I convert this binary with the 'single' option to a image file
  3. I program the binary data starting with address 0x0000 to internal SPI flash

Is this correct?

Oliver
