Compatibility table for nRF51422

[Nestor Matas]

Is there any compatibility table for nRF51 series chips with revisions, softdevice versions and SDK versions?

I have some custom boards with a module that contains a nRF51422 CEAA A0 (0x0031) and although I can reprogram the softdevice downloading the S310 or the S210, I have issues when trying to run ANT examples from the 5.2.0 SDK. The issues include hardfaults that occur when opening the ANT channel.

Will I be able to use softdevice 310 if I go back to SDK 4.2.2,?

I'm using Keil 5.10, SDK 5.2.0, SD310 1.0.0

I'm not able to read the markings on the chip as it comes inside a module. I will destroy it if I take apart the shielding. The nRFgo Studio says it is a CEAA A0 (0x0031) Using nrfjprog procedure I read 004B0031 at 0x1000005C, so it says it's a CEAAA0 too.

I know you don't recommend using this old chip, but it's all I have. 10 protos with this, and I'm not sure when the manufacturer will send me more with new chipsets.

What I don't understand is that if I erase the chip and download a new softdevice, nrfgo studio will tell me that the new sd is actually the one i've downloaded. If it is a CEAAA0 that shouldn't be possible, right?
