Time Base Registers in Zynq Ultrascale+ MPSoC

msauerpb over 1 year ago

Hi,

are there time base registers, like the TBL/TBU register in PowerPC 405, in the UltraScale+ MPSoC? How can I emulate such time counters?

Thank you for your help.

Hi Martin:

I am not a SW guy. However, I found this thread, which might give you some hints:

arm: Move tbu to arch_global_data

ZynqMP SoC is ARM core. A lot of u-boot source codes could be very similar between Xilinx ARM cores.
