sdk8.0.0: What happened to NRF_FICR_Type.INFO?

[Clem Taylor]

What happened to NRF_FICR_Type.INFO and FICR_INFO_Type in nrf51.h?

This was in ./components/drivers_nrf/hal/nrf51.h in nRF51_SDK_7.1.0_372d17a

but is missing from ./sdk/components/device/nrf51.h in nRF51_SDK_8.0.0_5fc2c3a

I'm using the QFAC and I added a check of NRF_FICR->INFO in my bootloader to make sure that the newer part is installed.

It this just a merge issue or is the info data going away in future nrf51 revisions?

This code:

if (NRF_FICR->INFO.PART != -1UL)
    debugMsg("device: %lX (0x%lX) %luK sram, %luK flash (variant %lX, pkg %lX)\n",
        NRF_FICR->INFO.PART, NRF_FICR->CONFIGID & 0xFFFF,
        NRF_FICR->INFO.RAM, NRF_FICR->INFO.FLASH,
        NRF_FICR->INFO.VARIANT, NRF_FICR->INFO.PACKAGE);

Will would print:

device: 51822 (0x84) 32K sram, 256K flash (variant 1004, pkg 0)

It was decided that it would take too much effort to populate that region at production, so it will not be a feature on newer revisions.

Could you qualify this?

It is present in the rev 3 nrf51822-QFAC samples I received from nordic. I was under the impression that they where production samples.

When you say 'newer revisions' do you mean revisions after rev 3 or do you mean rev 3 parts?

I was going to use this feature to make sure that the factory installed the correct part, but realized that the bootloader will most likely just crash if a 16K part is used instead of a 32K part.

Sorry for being unclear. I mean revision 3 parts. Some of them may have the region populated, but it's not a feature anymore.
