Hi all, I'm currently building a bootloader suitable for Dual Channel DFU and SD132. It is on nrf52832, currently on PCA10040, using SDK 14.0.0.
Although the linker script works, and creates a hex file, I am left with an error_code 1 after nrf_sdh_enable_request(), from sd_softdevice_enable().
Is it the Linker Script's fault? Have I completely missed the mark? Or is it something completely different. Feel free to ask for more details, I've included the Linker Script, as I'm unsure of what else to add.
Thanks
Below is what I have so far, cobbled together from the various examples in the SDK.
