About AGM chip program

[cn0xroot]

Description of the feature you're suggesting.

I purchased a PortaPack H2. During use, the AGM chip was damaged, so I replaced it with a brand-new AGM chip myself. However, the screen does not display anything. Does this chip need to be programmed? How should I proceed? Thanks

Anything else?

Honestly, I don't know.
Maybe @zxkmm can give a hint, I know he changed some screens and have knowledge on the topic.

I had never play intel or intel-compatible CPLD.

But for common procedure, you write or generate the HDL code in IDEs like vivado (in this case, use the intel one instead, but I forgot the name)

Then flash it with programmer (usually each brand has its own programmer), by connecting the port (usually jtag)

So if you don't want to code yourself, what you should do is asking whoever sold the portapack to you, for the code or a programmed chip. Because we didn't write that so we don't have them.
