I was trying to upgrade my Holux gpsslim 236 to the 3.2.4 firmware using siftdemo 3.83 and sirfflash version 2.15. I'm using BT in order to connect to the GPS. I was able to switch to sirf mode and send the 94 command to the GPS, while trying to flash the gps I'm getting the following error "unable to get target external bus width info".
I would like to add that,I was able to see on the BT software that the sirfflash was able to connect to the GPS.
