Hi. I've developed a custom board on an old E0 51422 chip with SDK 6.1 and SD110 7.3.0. Everything works fine with that setup (SPI, interrupts, timers, etc). Got new batch of chips of version H0 (yes, thats 51822) and external intererrupts stopped working (everything else seems more or less fine tho). So I decided to try to upgrade my application to whatever latest supported SDK version. I've been trying to get to run 8.0.0, 10.0.0, 12.0.0 and 12.2.0 version blinky examples with no luck (following this tutorial devzone.nordicsemi.com/.../). It seems that they just go straight to hardfault, at least according to debugger. As I understand, there should be no difference between writing for 51422 and 51822, it's just a question of having ANT? I'm on arm-none-eabi compiler v5.4
Any suggestions on how to get the magic running?
