Can you please share a link to latest bootloader which will have zoom3 support. I am using L25_INC3.x android kernel. The board hangs as soon as it boots the kernel. Enabling the logs shows us that the hang occurs when UART3 clocks are being disabled in omap_hwmod.c as mentioned by Lei Ming. Has anyone observed this issue on any of omap boards? > ~sanjeev > >>
