Description

The NXP (formerly Philips) LPC2000 family of ARM MCUs was sufficiently different from other ARM variants that I decided that a forum dedicated to it would be useful. The group also caters for other LPC ARM chips such as the LPC3000 and LPC1000 families.

I don't need a lengthy explanation as to why you need to join the group, I only set it up like that to keep out spammers. Everyone gets approved! First posts are moderated so they might be delayed, please don't resend your message.

Do not upload any copyright material to the group's Files area. It will be deleted and the offender banned from the group.

The Group's file space is limited; if possible add a link to the files in the Links section. This will also get over any copyright problems.

Bogdan, when trying to bring up our first board with a LPC2478 we did have similar issues with the SDRAM, the behavior or the SDRAM was totally unpredictable

Re: LPC2468 interface with MT48LC4M16A2 (4Mx16) SDRAM
Hi Bogdan, Well...it seems there might be a problem. If the bank addresses (A13-A14) are not hooked up right how will the SDRAM work? You would be stuck in

Ok, better break this down another step. 1) Schematic, can you post a PDF of the interconnect or PM? 2) Do you have a scope to look at various signal timings.
