Hello,
I've tried to use J-Link to flash BeagleBoard rev.B4 with cpu OMAP3530 (Cortex a8 core).
On PC I have Ubuntu 11.10 so I installed drivers for jlink on linux (use V4.41g).
Firstly, as I wrote in my previous post I take error about low supply voltage level.
After making simple converter from ARM 14-pin JTAG to TI 14-pin JTAG this error disappear.
But now I take new error:
