Matter resolved by adding in the XTAL warm-up time to be 5000...
From the post...
I confirm that issue was due to crystal warmup time.
We manage to resolve this issue in firmware by doing the following:
1 - create a CSG file inside the application folder named app.csg with the content below:
ENTRY "PMU Crystal Warm up Time"
"Crystal warm up time" = 5000
Note that the default Crystal warm up time is 2500. By increasing this to 5000 we managed to resolve the issue.
2 - Add the following line to makefile.inc in the same folder:
GS_LIST += $(DIR)/app.cgs
This trick only works in SDK 1.1 and does NOT work in version 1.0.1.
