Mapping HWID to revision information

[pabigot]

This thread provides some references for those of us who need to have firmware that runs on multiple releases, but don't necessarily know what revisions are in the field. Unfortunately, the new release 2.0 of nWP-21 removes all the tables with HWID to build code, tested versions, and other useful information.

Will that material be re-appearing in a new white paper, preferably with more complete information? Please?

Hi

For nRF51 SDK 8.1.0 there is a new function

void nrf_ic_info_get(nrf_ic_info_t* p_ic_info)  

that can be called from your application which returns information about chip revision, RAM size and ROM size. More information in \SDK v8.1.0\components\libraries\ic_info\nrf_ic_info.h

Update 11.6.2015 The above function should work for all nRF51 revisions, i.e. revisions 1, 2 and 3. I have tested it with several SDK versions:

• nRF51 SDK 8.1.0 (compatible with nRF51 rev 3): Works
• nRF51 SDK 6.1.0 (compatible with nRF51 rev 2 and rev 3): Works
• nRF51 SDK 5.2.0 (compatible with nRF51 rev 2): Works
• nRF51 SDK 4.4.2 (compatible with nRF51 rev 1 and rev 2): Works if you replace "SIZERAMBLOCKS" with "SIZERAMBLOCK[0]" in line 22 in nrf51_ic_info.c

To check the IC revision, RAM size and Flash size, copy the nrf51_ic_info.h and nrf51_ic_info.c files from SDK 8.1.0 into the SDK that you are using and call the function mentioned above.

Update 25.5.2016 HWID/FWID list may be described on this thread.

Most of them? nRF51822-PAN-v2.4, example #17: RADIO END to START connection using PPI or short is not functional applies to nRF51822-QFAA-C0 not to nRF51822-QFAA-G0. In the rev 3 PANs 69 and 71 apply to QFAA but not QFAC.

Unless I misunderstand what those tables are saying.

(Thanks for confirming the code can be used independent of chip; it'd still be nice to have it backed up in documentation; it makes me curious where the other bits of that word carry information I could use.)
