Other Parts Discussed in Thread: AM5728

Hi,

We need to know the differences of AM5728 SR 2.0 processor w.r.t. the SR 1.1 processor. Please let us know if there is any delta document or migration guide describing the differences.

Hi Biser,

Thank you for the information.

In the migration guide, I observed that the manual IO delay timing is updated for AM5728 SR 2.0 processor.

Can we use the updated SR 2.0 manual IO timing with SR 1.1 processor ?

Regards,

Elvin

There are separate datasheets for SR2.0 and SR1.x. For SR1.1 you should use data from the corresponding datasheet (latest was Rev. P).

Regarding pinmux, there is a new section 18.4.6.1.1.1 in the AM572X TRM Rev. E.

Hi Biser,

I have gone through section 18.4.6.1.1.1 of AM572x TRM Rev E, which explains about the procedure for permanent PU/PD disabling of gpmc_a[27:19] pads.

However I wanted to know if there is any pad muxmode (bits [3:0] of CTRL_CORE_PAD_xx register) change between AM5728 SR 2.0 & SR 1.1 processors.
