I'm complete nordic newbie and asking you for some help.
I have 2x 81522 ICs, one is QFAAC0 and the other one is QFAAH1, both QFN48 packaged.
(1) looking at infocenter.nordicsemi.com/.../nRF51822_ic_revision_overview.html
=> I wonder what are the IC-rev of my 2 chips ? C0 seems a IC rev 1 (right?) and what about H1 ?
(2) looking at infocenter.nordicsemi.com/.../nRF51422_nRF51822_ic_rev_sdk_sd_comp_matrix.html
the doc says: ICrev1 (QFAAC0) means an SDK 4.4.2 with SD110 5.2.1 ... however the SD110 5.2.1 binary image release notes says that it requires an SDK 5.2.1 ...
=> I wonder who I should believe? At the end, is it ok if I flash a SD110 5.2.1 image and use the related 5.2.1 SDK ?
QFAAC0 is a rev 1 chip, QFAAH1 is a rev 3 chip. To save yourself a lot of headache I recommend that you use the rev 3 chip, and the latest SDK and SoftDevice. SDK 11 and SoftDevice S132.
thx Øyvind. I was (and still am) confused about the doc referring to Hx0 and not Hx (where x=0..9). typo?
As the annotation says "3) The x in the build code is 0..9 for production release."
ah ok! now I understand. the 0 is not mandatory. my confusion comes from that "Hx0" reads as a 1-letter + 2-digit (with 0 as the fixed second) e.g. H30, whereas Hx means 1-letter + 1 digit e.g. H2.
