Thanks

Its a mistake in this repo

github.com/.../armgcc_s130_nrf51822_xxaa.ld

I've raised an issue with the author, as it looks like the RAM start address and also the RAM length are both wrong

Yes that's very wrong, S130's user ram start address is 0x20002800 (you missed a zero in your latest reply).

Edit

Thanks

I think the issue is that the linker file is not allocating enough RAM to the SD.

The RAM start address is being set to 0x20002080 , which I think is too small

I think this is typo and the value should be 0x2002800

I'll change this and try again

Thanks for your help

no that's about it - change the flash start, change the ram start. If you're using gcc just crib from one of the .ld scripts located in the examples directories.

1c000 is right for the v1 softdevice, v2, just incase you loaded the wrong one, is 1b000.
