Identifiying the Zynq

[fernslayer]

Hello,
how does one identify which Zynq (7010 or 7020) is on the parallella board? Does /proc/cpuinfo contain data that can be used to distinguish them?
Thanks

You can read the part number on the top of the chip.

Not certain if you can ascertain the part from /proc/cpuinfo. I mean, there is CPU variant and CPU part, but I couldn't say for sure if either maps. With a 7020 I have:

CPU variant : 0x3
CPU part : 0xc09

I don't have a 7010-based system to try this with for comparison.

Cheers,

Andrew

According to the Zynq TRM there is a PSS_IDCODE register at address 0xF8000530

PSS_IDCODE(16:12) contains 0x02 for 7010 and 0x07 for 7020.
Other bits seem pretty constant PSS_IDCODE(27:21) is 0x1B, PSS_IDCODE(20:17) is 0x9. (Bit numbering starts as zero within the word.)
