Title: FTDI EEPROM Default
Post by: aphon on May 11, 2020, 05:51:54 pm
Hi,
it seems I bricked my bus blaster. Urjtag keeps on complaining that tdo is stuck at 1 when trying to program the onbard CPLD. I already excanged the CPLD and the FTDI chip but it didnt help. I found out via FT_Prog that the ft232h chip is blank.
Can anybody please send me his/her eeprom content so I can write the data to my bus blaster?

I own the bus blaster 4.1a and try to program the onboard cpld with urjtag:

->cable jtagkey
->detect

thank you very much in advance,

AK

I have this problem also. New Bus Blaster v3 from Seeed Studios with a blank EEPROM. If I cannot find a solution then I have a brick.
