Note: On Colibri VF61 the JTAG pin JTMS is also used by the on module audio codec. When the operating system (WinCE or Linux) is started, this pin is muxed for audio codec communication use, hence the JTAG connection will break! On Linux, the pin muxing can be avoided by compiling the kernel without the audio SoC machine driver (CONFIG_SND_SOC_FSL_SAI_WM9712).
I need some clarification on what happens when the OS is started on A5 core: is there a way to have JTAG working when A5 runs WinCE 6?
Or, how can I stop the boot of WinCE 6 on A5 core (so that JTAG works)?
