14.x iMPACT - PROM File Formatter - Cannot create .mcs file for the XC3S50AN in PROM File Formatter
When attempting to create a .mcs file for XC3S50AN in PROM File Formatter from iMPACT 14.2, I see the following error:
ERROR:Bitstream:25 - 0xd5ae bytes loaded up from 0x0 would exceed promsize 0x8000.
This is an issue in iMPACT from version 14.2. It will be resolved in a future release.
To work around this issue, there are two options:
1. Roll back to a previous version of the software.
2. Use PROMgen to create the .mcs file, for instance:
promgen -p mcs -c FF -o SP3AN -spi -u 0 top.bit
This issue will be resolved in a future release of software.
