McASP revision identification of AM335x ?

Hi,

MCASP0/1 Rev Register of AM335x not consistent with TRM.
22.4.1.1 REV Register (offset = 0h) [reset = 44300A02h]
The read result of this register is 0x44307B02.
Is it an error in writing of TRM?

Best Regards,

Shigehiro Tsuda

    Hi,

    I think you may be correct, I verified your results on my AM335x Starter Kit, running the latest SDK.
    Read to MCASP0 REV register returned:

    root@am335x-evm:/etc/init.d# devmem2 0x48038000
    /dev/mem opened.
    Memory mapped at address 0xb6f46000.
    Read at address 0x48038000 (0xb6f46000): 0x44307B02

    You can use the link Submit Documentation Feedback at the end of each page in the TRM to report this misalignment.

    Best Regards,
    Yordan

    Hi Yordan,

    Thank you for your quick reply.
    I understand that TRM of AM335x is typo.
