Using Linux 3.x kernel and debian 6.0 stable distro.

USB flash program 1.3

http://code.google.com/p/mphidflash/

libhid 0.2.16

I have installed a Generic HID bootloader? and a basic p18F2455 circuit setup for reading and writing USB data.
20mhz crystal no LEDs one jumper for bootloader mode and a switch for reset., nothing special.?

When I plug it in and use the "dmesg" commandline program I get.

Now this I had hacked around on mphidflsh to see if I could track it down.

./mphidflash -v 2233 -p 7001 -e

Turned on debugging and added some extra check points and I added data into the default buffer and added a second buffer to make sure it read it to a clean buffer. As you see the only data that is read back is one byte into the second buffer.Writing of the initial buffer gave no errors.

./mphidflash Error: USB read error

Tracked the error down to this function in mphidflash.usb-linux.c

??? if(HID_RET_SUCCESS != hid_interrupt_read(hid,0x81,usbBuf2,64,0))

What would cause libhid to return error on reading while writing is fine?

If you download the latest Microchip USB stack, there is an HIDAPI
based cross-platform HID bootloader, you may want to try that one,
it works for me whereas mphidflash did not seem to work for me
(PIC18F87J50 USB PIM) last time I tried it.

Ok could not compile Qt4.7 packages because of the? Debian 6.0 stable distro,
it seems compiling for the Microchip HIDAPI needed some newer libuuid functions
.so I changed my /etc/apt/sources.list distro setting for source downloads to testing instead of stable

deb-src http://ftp.us.debian.org/debian/ testing main contrib non-free

updated my apt repo :

apt-get update

downloaded the source for util-linux which contains the libuuid

apt-get source util-linux

uncompressed the tarball ,recompiled and installed and qtcreator compiled fine..
http://qt.nokia.com/downloads

Next will be to see if the compiled bootloader actually works now. Thanks for the help.

I tried to get the Microchip HIDAPI Bootloader to find my 18f2455 chip

and it would not. Just says disconnected at the bottom and give me no
options other than to kill the window.? The chip is in boot loader mode
i.e RB4 to ground and 10k to 5v usb + bus. It also shows up in the dmesg & lsusb list.

I was in the wrong on this one, I was using the Bootloader firmware form the Generic HID Bootloader.
I installed the accompanying HID Bootloader for the HIDBootloader and it all worked. or at least found
it will now test the uploading.

Thanks for your help.

Well I had tried out the bootloader and I get the same problem. It writes to it as it says Querying Chip.
but then it gets disconnected when trying to write from the chip. No difference in the problem of either program.

I was told that D+ was the write to chip line and D- was the Read from chip line.?
checked out the connections they seemed to be good, but will debug the lines later
have to go somewhere. Wondering what could be the deal on this chip and bootloader if it has a not
read option or should it be readable from the get go?

Hmm, it seems you need to read the ABCs of USB before embarking
on this project.

As for your issue, you may want to check if your hardware and
firmware are correct or not. If possible, get a known-good hardware
(eg: the dev kits from Microchip) and then use the known-good
Microchip USB firmware framework to get familiar with the
stack first.
