After flashing a newer u-boot my Sheeva has become very quiet.
$this->bbcode_second_pass_code('', 'usb start
ext2load usb 0:1 0x0800000 u-boot.kwb
nand erase 0x0 0x60000
nand write 0x0800000 0x0 0x60000
')
u-boot.kwb is from https://people.debian.org/~tbm/u-boot/2 ... heevaplug/
Now I don't get any response
$this->bbcode_second_pass_code('', 'sudo cu -s 115200 -l /dev/ttyUSB0
Connected.
')
This remains uninterruptable (ctrl+c) until sheeva is powered off.
Next idea was to use openocd, compiled freshly from git
$this->bbcode_second_pass_code('', '../src/openocd -f board/sheevaplug.cfg

Adding the parameter -c "adapter_khz 100" has no effect.
The device is still recognized
$this->bbcode_second_pass_code('', 'lsusb

Any idea what to do now?
