7i90hd. Problem with writing bit file was created by kulek
Hello. After incorrect firmware loading all three LEDs on the board light up and mesaflash not found board. I try jtag flash. The firmware is uploaded successfully and light up only yellow power led. Mesaflash found board, but when I try to write a bit file an error occurs: Error: BootSector is invalid.
--fixbootblock doesn't help. What shoud i do to wrtie bit file in EEPROM?

Does the alternate EEPROM still have a valid image?
(that say mesaflash --readhmid works with)

No it does not. After unsucsessful firmwareI I tried to boot from the second EEPROM (W3 in the low position). But Mesaflash not founded 7i90 and 2 leds glowed ( power and int ) opposit to 3 in first case.

Did you try writing one of the standard supplied EPP bit files?

Hard to tell if this is a EPP interface issue or maybe a Mesaflash problem
Can you try:
Power up on alternate EEPROM (which should have a valid boot sector)
program FPGA via JTAG (NOT FLASH!)
Then try mesaflash again to write a standard EPP bitfile
If this does not work, a temporary workaround (if you are building you own firmware)
would be to write the flash via JTAG
