Hello,

I'm trying to upload a Linux rom filesystem to Flash memory on the Microtronix Stratix Development board. The SODIMM flash on this board is 8MBytes and ranges from 0x800000 to 0xFFFFFF.

I have the linux kernel in flash at 0x800000 and it is roughly 900kbytes and extends to around 0x8DD000.

The S-records in the romfs.flash file begin at 0xA00000 and extend up to 0xEE33E0 which is roughly 5.125 Mbytes. Since the portion of the flash memory I wish to use extends from 0xA00000 to 0xFFFFFF (6 Mbytes), this should fit with no problem.

However, when I try to upload romfs.bin through the Nios II IDE, I get the following error message:

I've also tried uploading the romfs.flash file directly from the Nios II SDK shell commandline and get a similiar message:

Does anybody know why 5Mbyte of data is too large to fit into 6 MBytes of Flash (0xA00000-0xFFFFFF)?

Thanks,

Terry
