Hi,
An experience:
I can debug the linux kernel with both openocd + TIAO/flyswatter2/.. or the
TI dongles like blackhawk with CCS.
Note, one very tricky thing: Recent linux kernels mess with the jtag during
boot on the bbb. You need a kernel patch -just- to be able to debug:
*diff arch/arm/mach-omap2/omap_hwmod_33xx_data.c*
*diff --git a/arch/arm/mach-omap2/omap_hwmod_33xx_data.c
b/arch/arm/mach-omap2/omap_hwmod_33xx_data.c*
*index 6b406ca..8cb0b85 100644*
*--- a/arch/arm/mach-omap2/omap_hwmod_33xx_data.c*
