Breaking changes on early MityARM

Added by Nigel Doe over 10 years ago

I have an early MityARM module and dev kit. On trying to implement the latest software versions I found that the Ethernet interface was not functional. On investigating it appears that there has been a pcb change on the RGMIII_RESETn signal.

Are there any other significant changes such as this that I need to be aware off?

Thanks,

Nigel.

Hello Nigel,

Sorry about that. The description of the hardware changes for the Dev Kit baseboard are here:

The only significant change was the location of the ethernet PHY reset, on this page:

You should see a note about setting the "initphy" u-Boot script to toggle the "old" GPIO position for -1 and -2 boards.

Should have spotted that note but somehow managed to miss it!

Thanks,
Nigel.
