LA1224-RDB-BHS schematic

Hi,

We have a LA1224-RDB-BHS development board and are trying to use various interfaces on it but are occasionally hitting problems. Can you provide a full schematic?

The user manual (UM12137) does not provide enough detail.

Thanks

Nigel

Hi,

Sorry I've no idea what the schematic number is. Neither the User Manual (UM12137) or the User Guide (UG10144) make any reference to a schematic that I can find.

Thanks

Nigel

Hi,

Having taken the case off now, there are a couple of numbers on the board itself, they are 'SCH-54991 REV A' and below that '700-54991 REV X4'.

Thanks

Did you sign NDA with NXP?

Would you please provide your NDA number?

Hi,

The schematic is certainly useful. But any reason why the schematic is called LA1224-RDB-BHS_Glasgow_54991_A1.pdf and yet the LA processor used in the schematic is an LA1235 and not an LA1224?

Thanks

Nigel

Reading the info from the processor it does look like we have an LA1235 on it, just a bit confusing.
