Hi, I've been trying to get the bletiny and bleprph apps running on a few types of nrf51 boards but not having much luck.
The 3 types are: 1. PCA10000 - QFAA G0 (The stubby little USB dingle with the built-in Jsegger J-link) 2. PCA10024 - QFAA G0 (The mbed enabled board, using a hex file ) 3. BBC:Microbit - QFAA M0 I've tried with bsp set to 'nrf51dk-16kbram' and 'nrf51dk' I am uploading the Newt boot loader app too. In order to upload to #2 & #3 (as they appear as USB drives) I've tried converting the elf binaries to a combined hex file in two different ways: A) arm-none-eabi-objcopy -O ihex bin/bletiny/apps/bletiny.elf app.hex arm-none-eabi-objcopy -O ihex bin/nrf51_boot/apps/boot/boot.elf boot.hex mergehex -m app.hex boot.hex -o microbit_firmware.hex B) srec_cat boot.hex -intel app.hex -intel -o combined.hex -intel I'm pretty sure for #3 that it's possible to flash the entire address range of the nrf51 as the micro:bit's default firmware download from the web is a > 500k hex file; which without lifting the hood it implies to me it has the SoftDevice, App and Bootloader. I'm not having much luck, I probably need to add some load/start address info during objcopy and/or some address altering flags using srec_cat (?) Are these boards and the methods currently supported? I guess they should be but I've buttered fingered something somewhere. Or perhaps should I be using the 'official' nrf51dk ? All the best Wayne
