Consider 2 x 2 GB about trellisboard HOT 5 CLOSED

What is the source for these chips? I can't find any DDR3/DDR3L 16Gb x16 chips stocked by DigiKey. Going to two 8Gb chips for 2GiB total might be an option, but these seem to be about $26 each on DigiKey so not super cheap. I suspect most applications needing this much memory will be bottlenecked by the maximum clock frequency of the ECP5 anyway.

I have never used them so I can’t vouch for them, but https://www.components-center.com/product/Micron-Technology-Inc/MT41K1G16DGA-125-A.html

I strongly disagree with your assertion though. If you used this board for running Fedora/RISC-V, then 1 GB is very limiting. The argument I got from Fedora for why they wouldn’t support 32-bit RISC-V is that they have packages that can barely compile in 4 (or was it 2?) GB.

Aiee, the qty 1 was a misread, sorry. It’s qty 1020 but it doesn’t fundamentally change what I wrote.

Seems like this part is now obsolete - https://media.digikey.com/pdf/PCNs/Micron/PCN-32255.pdf - so probably not a good idea to design it into something new. However, I will consider going up to at least 2GiB (two 8Gb chips) for the next revision as I can see this use case now (although compiling packages that need >1GiB RAM on a 100MHz system doesn't sound like a great deal of fun, adding swap into the equation won't help either)

Reasonable if you expect to produce more than 500 of these boards, but if they are pin compatible and just a part swap away, I’d personally just stock up and use them.
