ST rev H & agranlund ram troubleshoot (solved)
Re: ST rev H & agranlund ram troubleshoot (solved)
@exxos yeah that's what I thought but nope, had to swap the two over, otherwise the byte order got swapped.
If it ain't broke, test it to Destruction.
Re: ST rev H & agranlund ram troubleshoot (solved)
Doesn't make sense as BANK 0 is basically the same and that would mean that would have to be swapped as well

Re: ST rev H & agranlund ram troubleshoot (solved)
@Steve you managed to run 4MB ram from @agranlund. I started the assembly but I can't start it properly
Re: ST rev H & agranlund ram troubleshoot (solved)
What is it you need to know?
If it ain't broke, test it to Destruction.
Re: ST rev H & agranlund ram troubleshoot (solved)
I have everything soldered according to https://github.com/agranlund/STRam
Do I have to make a mod for 4MB to work properly?
Is it enough to do as described by @agranlund

Re: ST rev H & agranlund ram troubleshoot (solved)
@dragmar yes, remove all the ram first, then install the ram board and then connect up the wires but note that CAS1H and CAS1L are incorrect and need be swapped over.
If it ain't broke, test it to Destruction.
Re: ST rev H & agranlund ram troubleshoot (solved)
Here is the changed EAGLE files and Gerber files made out of it. Bodge wire is not needed and swapped CAS1L and CAS1H on the silkscreen. Read README2.TXT for full info. Board tested and working.
I have included:
The Original github zip.
Photos of the board from Christian Zietz.
Schematics.
My changes above.^^
