Peripheral examples working fine, BLE examples not working

[kylobyte]

Hi all,

getting burnt out from searching the fourms and finding dead ends or outdated answers so just posting a question quickly.

Somewhere along the line my nrf51DK has stopped working with the ble examples, not sure what has changed,

I'm now running SDK 12.3, soft device 130 v2

 when using the DK and uploading ble app uart example kiel says  error flash download failed : could not load file nrf51422_xxaf.axf

running the non ble examples are fine.  not sure what happened but it use to work, i think i was using sdk 10 possibly..

I've tried fresh copies of the sdk and examples, also erasing and programming with nrfgostudio, and also running the examples separately from pack installer. no dice..

I've gone through the s130 v2 manual for base irom and iram [section 15.1.1] which says  (0x0001B000 and 0x200013C8 respectively) with both my nrf51822 qfac and nrf51dk having 32k ram (0x8000) and 256kb flash (0x40000)   this doesn't work.

when i reload keil with a fresh BLE_APP_UART  the values for pca10028 s130 sdk12.3 are different which is confusing IROM 0x1B000 : 0x25000 and IRAM 0x20001FE8 : 0x6018

Why is this? any thoughts?

nevermind, after hours and hours and days and days of continuing to search for small technical details and infuriating searching it turns out my directory path is too long.  I had it extracted to  /my documents/design and that was enough to overflow it. is anyone else baffled by the user unfriendlyness of nordic development?
