Hello,
I had previously purchased an RM57 HDK for evaluation. Unfortunately, I am running into one of the issues described in the Silicon Revision A errata. I am wondering if there is any chance current HDKs are being shipped with Revision B of the RM57?
Thanks for any help.
This may be a less than appealing option - but assuming that you can purchase the Rev B silicon (*)
the HDK is designed to accept a socket ... I *think* this is the part # SG-BGA-6033.
The socket it accepts has an elastomer with vertically conductive wires - so if you remove the BGA on your board, clean the pads up well so that they are flat, and bolt on the socket - the new part can go in with just compression and not soldering.
The sockets are expensive at about 2x the cost of the HDK so that's why we don't put them on every HDK but we use them in our team to swap parts out - here's what it looks like:
If you think this is of interest - I can dig up the exact part #.
Regarding the RevB silicion - I can't tell what's available just by looking at TI.com because the silicon revision of the TMP parts (which are what's available) isn't part of the part #, it's encoded in the lot #. Only the part # shows up on the sample page and could be either. Would need to check with someone who has better visibility into the inventories to see if this is rev A or B.
So that's something we'd also need to make sure gets run-down before you go down this type of path. Anyway if it's something you want to do we can run down the details on the rev. and the socket part #.
