SAME53 chips in 64-pins packages, of Revision A, do not have functional Ethernet module (pin GRXDV not available).
It should be fixed on Revision D chips.
Problem is - where to get them ?
I have sent emails to tech.support of main suppliers/distributors with following result:
- some of them admitted they do not have such a detailed information about chips they sell, so they don't know Revision
- some others didn't answer for >3 days, so I am skeptic they ever will
Could please anybody confirm recently bought any SAME53J19A.. or SAME53J20A.. chips of Revision D, i.e. Device Signatures 0x61830305 or 0x61830304 ?
Please state which distributor & order code.
