QFAA H0 examples don't work

[stiebrs]

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?

Hi Stiebrs,

When you tested with blinky example, it was the blinky without softdevice or the ble blinky?

In the SDK we provided some pre-compiled hex file in each example, could you try to test ?

We usually suggest users to use GNU ARM v4.9 could you give it a try ?

Hi Hung Bui, I've been trying to run blinky without SD. Precompiled hexes are of no use to me, because I have a custom board with LEDs on P15/16, and from devboards I have only old PCA10000 and PCA10003. Tried building with 4.9 and debugging:

Right. Linker file was written for QFAC chip, which has 32k of RAM, while I was using QFAA, which has 16k. Fixed linker script and now it works.
