Honored ContributorI have a Cyclone III EP3C5 design that uses an EPCS4 device in AS mode for remote system update. my question: what file format am I supposed to use when downloading a new application configuration into the EPCS16?.rpd or .rbf or else?
Please help. Thanks a lot in advance
Honored ContributorI use quartus 9.0，same as you，i just see symbols ,that‘s doesn't matter
Honored ContributorThen what did you write into EPCS? How did you applied bit-reversal to each byte before writing into EPCS? You mentioned that you used I2C, so you must had some byte to transfer. You can't transfer symbols. I think you might be reading the file in some way and that's why you didn't bother about the contents of the file. How did you do that?
Honored Contributori think you make this too complicated,CPU deliver the .rbf file without any change,
i did bit-reversal in fpga as foll assign d_to_E[0] = data_to_EPCS[7]; assign d_to_E[1] = data_to_EPCS[6]; assign d_to_E[2] = data_to_EPCS[5]; assign d_to_E[3] = data_to_EPCS[4]; assign d_to_E[4] = data_to_EPCS[3]; assign d_to_E[5] = data_to_EPCS[2]; assign d_to_E[6] = data_to_EPCS[1]; assign d_to_E[7] = data_to_EPCS[0];
