[Thinkfinger-devel] Thinkfinger on Arm

[Nataraj S Narayan]

Hi

I am having a problem with thinkfinger-0.3 in an embedded Arm9 board
(ATMEL AT91sam9263-EK) with linux. I tested on Angstrom RFS as well as
debian Armel Lenny RFS. Using kernel 2.6.28 patched for At91sam9263.

The driver and commands work very well in a normal Debian PC.

While the #tf-tool works well in normal Linux PC, it gives the
following error always on the Atmel board, be it Arngstrom or Armel
file system.

Please help me to get this fixed. We thought it could be a problem
with power supply. But after giving an external power of 5V--2.0A ,
the output is the same.

Vaaraahi:~/thinkfinger-0.3# lsusb
Bus 001 Device 002: ID 0483:2016 SGS Thomson Microelectronics
Fingerprint Reader
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub


Getting the following after enabling usb-debug.


Vaaraahi:~/thinkfinger/tf-tool# ./tf-tool --acquire
