I went to update my firmware, and I immediately had strange behavior from the HxC SD card emulator.
First, I backed up my SD card, then I formatted it to FAT32 via windows XP and a built-in SD card reader in a laptop.
Then I put the firmware *.upd file onto the SD card.
When I powered on the machine (Ensoniq EPS sampler keyboard), the LCD displayed a row of blocks on top, and did not make any noise. The red LED was blinking constantly.
I then tried formatting the card again, and I put my old files back on to it. Same behavior...LCD displaying just a line of blocks and red led blinking constantly.
I then thought, maybe I don't have the bootlader (is there a way to check which firmware version I was running?). When I formatted the card again and put the bootloader *.upd file on there, I now get an error code 5 ... bad file.
Has this behavior ever been reported before? Is there anything else I can do? Could it be a solder problem with the LCD because I did solder a ribbon cable to the back of it to relocate it?
What is your actual firmware version ?
