[Gumstix-users] i2c-load problemes

[Brian W. <li...@gm...>]

Hi all,
I have a system of:
Verdex XM4-BT
NetWifiSd (with wifi module removed)
Robostix

My current root is:
Revision 261M
Built on Mon Mar  3 22:37:16 EST 2008
Build machine: slapstick
Target machine: gumstix-custom-verdex
libc: glibc

I have compiled my own i2c-load, but I use a downloaded
i2c-Boot-m128-16MHz.hex
I have used i2c-test to verify the i2c and have programmed i2c-Bootloader
via uisp.
I have programmed the fuses with pgm-fuse-bootloader, and manually

When I try i2c-load 0xb Info I get the following output:
root@control:~$ ./i2c-load  0xb Info
ERROR: I2cTransfer: ioctl failed: Remote I/O error (121)
ERROR: I2cReadBlock failed
ERROR: Unable to retrieve boot information from i2c address 0x0b

dmesg shows:
root@control:~$ dmesg

<4>i2c: log: [00000446:000007e0]


For grins I tested this under buildroot and the effect was the same.

Any ideas?
