Other Parts Discussed in Thread: 66AK2E05
Hi all,
We are looking at 'SPRS864D', the datasheet for AM5K2E02, and in particular section 3.3.2 "Part number legend". The bottom field of this name is 25 or 4, 25 for 1.25GHz and 4 for 1.4GHz.
Is there a register to read that will determine this at runtime in the boot phase? I tried the JTAGID register (at 0x02620018) but this is the same for both SoCs.
Use case: need to have a boot image on both processors which can decide which settings to use for PLL depending on the core running speed.
There is also a ‘DEVSPEED’ register that in the datasheet looks perfect. But both the SoCs are reading it as 0x0 (both in C code and in the debugger directly), so that is not helpful.
Many thanks
