nrfjprog.exe with bin files

[BMW]

Hi, I'm trying to program my nrf52811 by using nrfjprog.exe with a bin file. It seems to work with a .hex but when I run the .hex through srecord to create a .bin and using nrfjprog.exe with .bin file, the device gets flashed but doesn't actually function as it does with .hex. What could be the issue?

Hi, 

nrfjprog.exe only support hex file. See nrfjprog commands.

That may be true for an older version but my version is showing that it accepts multiple filetypes including bin files.

Bin files don't contain any addresses like hex files do. So your SoftDevice and application start from 0x00 and contain data up to somewhere like 0x2d000. But the UICR starts at 0x10001000. So if you have UICR settings then now you get a bunch of padding between the end of your real data and the UICR. A quick test here spits out a 256MB bin file when I take one of your UICR dumps and add data at address 0x00. If you want to use bins though you could have two files: one for the SD + app and another for the UICR.

I'm a bit confused now. My hexfile that works only has data that writes up to what you were saying 0002d740, so how is it that it has data that is writing to 10001000? Also I don't think we have data writing to UICR for this.

[Daniel Veilleux]

That setting that enables the reset pin lives in the UICR, starting at 0x10001200.

Bin files cannot have "holes" and there is a huuuge gap between end of flash and UICR.

Only hex files support non-continous address space. I strongly recommend using them for this reason here.

I would but the current hex file is too large for the size of the flash, which is why I was trying to use .bin

[Daniel Veilleux]

If the code overflows the available flash then changing file types won't help.
