RE: HardFault in SoftDevice, PC=0x10000000

Thank you so much, that was indeed the issue and I would have never figured it out.

As a workaround, I picked the option to disable the FPU (by setting gcc to use the "Soft" floating point ABI), since I don't need it anyway.

Hello,

It looks like you have been unfortunate enough to run into errata 220 ([220] CPU: RAM is not ready when written). This issue is very rare, but it does happen in certain FW configurations. Please have a look at the discussion here: Random bad instruction faults at 0x16274 with softdevice s132 version 7.0.1. SDK 16.0.0 where I proposed a workaround for this.

[quote user=""]As far as I understand, this indicates that the CPU tried to jump to 0x10000000 and the LR was 0x16299, which is in the SoftDevice region.[/quote]

Yes, that is how I interpret the stack dump as well.

Best regards,

Vidar
