nRF5340 - reading silicon build information from code

[Gabriele]

Hi,
for nRF5340 the "Build code" is a string of 3 chars

H - Hardware version code
P - Production configuration code
F - Firmware version code

I'm wondering if one could read it programmatically

You can read the production config, part, variant, and package numbers from FICR.

See INFO.CONFIGID, INFO.PART, INFO.VARIANT, and INFO.PACKAGE.

Hi Haakonsh,
this is what I get

CONFIGID = 0x0112
VARIANT = 0x41414141

But how to interpret these numbers ?
Silk on top of chip looks like this
