please advise: how to progress further?

int ProgAlgSPIFlash::spi_flashinfo_m25p(unsigned char *buf)

but what value is pages and sector size?

Di you check the datasheet?

Sorry, low on time...

I tried this:

case 0x80:
  fprintf(stderr, "Found Micron M25PE Device, Device ID 0x%02x%02x\n",
          fbuf[1], fbuf[2]);
  switch (fbuf[2])
    {
    case 0x15:
      pages = 65536;
      sector_size = 65536;
      break;
    default:
      fprintf(stderr,"Unexpected M25PE size ID 0x%02x\n", buf[2]);
      return -1;
    }
  break;

Using Libftdi,
JEDEC: 20 80 0x15 0x10
Found Micron M25PE Device, Device ID 0x8015
256 bytes/page, 65536 pages = 16777216 bytes total

but no blinking on power up.

This looks like the part got programmed. Try to run a verify run!

jonathan> but no blinking on power up.

This looks like your FPGA boot mode is not right. Did it work in another
way?
Did yoy try e.g. with the Xilinx tools?

Bye

could you please elaborate on what might be done regarding:
"FPGA boot mode is not right" tx.

I did not save logipi_blink.bit to flash using Xilinx, but the author Mike has done so.

regarding verify:
