When I attempt to program the Bottom Boot P30 flash, the following error occurs in iMPACT:
How do I generate a PROM file to target a Bottom Boot BPI flash?
If a flash is Bottom Boot, how do I generate a PROM file to avoid programming the sector at address 0x0?
To generate a PROM file, use the following command on the command line:
In iMPACT, select the part name of the same density, use the above MCS file, and operate as usual.
One caution is that if the bottom flash has data previously programmed to the first 4 blocks, iMPACT will not be able to erase it, and thus configuration will not work.
Note: Take care to set the startup clock as CCLK in BitGen as PROMGen does not correct it.
