Cyclone I read-out external config cfi flash 28F256

[GKate1]

HI, I would like to readout external CFI flash connected to cyclone 1 fpga. I have only JTAG connection to fpga, so I need to bypass or bridge through an FPGA. I have installed Quartus lite toolchain. I detect by jtagconfig only device 1PC12 . Is it possible to configure fpga (in RAM) with some loader And run the readout? After reset FPGA might be configured from flash as before...or maybe some better way exists? Thank You

Hi,

In order to update the CFI flash then you will need to use https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_pfl.pdf. Currently Cyclone 1 FPGA has been EOL so I am sorry to tell you that I am not sure if this IP is suitable for you to update the flash as it is no longer supported.
