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.

Thanks @pabigot

I will compare the list in OpenOCD to the codes I already added to my local clone the Black Magic Probe.

With the Black Magic Probe, it also is supposed to require the RAM and Flash size for each variant, so for the device I physically have (which is a QF AC AA , I think) I can get the sizes from the product selector table.

I dont think OpenOCD lists the part number markings, and its quite time consuming to add them.

I think it would be nice for the Black Magic Probe to list what product code it thinks is attached as well as flash and RAM size, rather than just displaying that its an nRF51, but it looks like this is a moving target.

I wonder how companies like Segger keep up. I presume someone at Nordic sends them updates ?? If so, its a shame those details cant be published.
