I am trying to update my Open Bench Logic Sniffer (v1.04) but keep getting an error indicating the flash could not be erased. Prior to the error I placed a jumper between PGC and PGD on the ICSP header and reset the board. Both ACT and PWR led's are on. Any assistance appreciated.

I won't be much help, other to report I have repeated the problem with my v1.04 OBLS.   

Note, I did not place a jumper because the instruction appeared to suggest that was not necessary if both ACT and PWR led were on.

However, I got the same errors.

My Logic Sniffer ROM loader is v0.3 (November 9, 2010) as opposed to your Logic Sniffer ROM loader v0.4 (December 9, 2010).

i've found several different utilities to manage the PIC firmware and the FPGA firmware for these devices. information is scattered about unfortunately.

i've compiled a binary in the past using source provided by a github repo, and that can access the `APP` portion the board, which i believe is the FPGA portion, and can dump the contents in either HEX or bin, but have been unable to dump / backup the contents on the winbond chip using such provided utility.

however my OBLS provided a means to solder a jumper header for SPI connection that allows me to connect jumper wires, thus i was able to use flashrom in conjunction with a bus pirate i have to dump the current contents of the winbond chip on the OBLS, i did not have to provide any power to the OBLS as the bus pirate can supply 3.3V to power the winbond chip to access its contents. i haven't tried to update or erase the contents of the chip using flashrom with a bus pirate, as i still need to figure out what versions i want to run and i'm still trying to gather all the necessary information for this device.


i hope some of this helps.
