Getting "mphidflash Error: USB read error" when I try to upload program to 18f2455 chip #6

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Loading a boot loader with USB access on it using MPLABX & Pickit2. I used 
generic DEMO one from Microchip to compile with a 18f2455 chip set.

2. Placed it in a basic circuit with program & reset capabilities on a 20Mhz 
crystal. Nothing special.

3. Make sure I am root and run the program as rot and load a basic test2.hex
Which only consist of a blinking LED.
./mphidflash -v 2233 -p 7001 -w ../piccode/test2.hex

What is the expected output? What do you see instead?
It does not even get started uploading the test hex file to the pic I get.
 USB HID device found
./mphidflash Error: USB read error

What version of the product are you using? On what operating system?
mphidflash 1.3 : Debian 6.0 stable and Linux Kernel 3.0.8

Please provide any additional information below.

Prerequisites include:
1. The PIC must already be programmed with a compatible Bootloader.
2. The Bootloader must be running ready to receive the update, often there is a 
switch to choose between Bootloader & application.

As Vendor Id / Product Id are not the defaults for the Microchip Bootloader it 
is not clear that a compatible Bootloader is installed in the PIC.
