MCS file generation and device programming

[abelardogonzalez]

Hello,

I have a project for the ZC702 board. In this project I am using only the logic of the FPGA and the two ARMs are not in use at all. The .bit file is generated properly and is working fine, after download it via the JTAG the configuration is correct.

Now I would like to program the configuration device to avoid the need to use the JTAG every time the board is powered up.

In the bitstream options I ask to generate a .bin file, but for documentation it seems that is missing the header. For this reason I use the following command:

write_cfgmem -format mcs -interface SPIx1 -size 128 -loadbit "up 0x0 system.bit" -file boot.mcs

I load the file on the memory, no errors or warnings but the Init led stays red.

Any ideas how to debug this?
