Hi

Does anyone know how to program 2 ROMs, 1 on each half of an Atmel 28C256?

For example with. A 27C256, selecting 'Program' gives the option of specifying start and end addresses. With Atmel 28C256 selecting 'Program' does not give this option, only 'Split'.

I am using a Dataman 40 Pro with latest software.

Any help would be much appreciated.

Hello Simonevo10,

You can place the data in the buffer starting at any location using the "positive offset" options on the "Load" dialog. You can also use the "View/Edit buffer" window to manipulate the buffer data to the locations you need.

I hope this helps.

Best regards,

Many thanks for reply Neil.

Can I please confirm that for programming 2 halves of the 28C256 on load file option that positive offset would be 00000 for programming first half, then postive offset to program second half would be &7FFF.
