Tool/software:
Hi,
I am having an issue with pin configuration so the pins would output the Trace. I followed the steps from Lauterbach's cmm script and the pins are still fixed to 0V (I connected to TRACE_CLK pin with logic analyzer and there is no clock present after starting to trace - trace components get correctly configured for sure).
I tried with multiple trace sources including XTALCLK that is surely generating clock - checked with logic analyzer and I can measure 25 MHz. Tested with multiple dividers as well, but without any luck. I can confirm that the TRCCLKOUT_CLK_STATUS register reflects correct configuration.
I configured PR0_PRU1_GPIOn registers to use MUX_MODE 4 as it is described in AM263x Sitara datasheet.
Does anyone have any possible solution? A comment from Lauterbach's script really caught my eye.
; * SW3.1=OFF, SW3.2=ON, SW3.3=OFF, SW3.4=ON
; This is the only boot mode where I could get the off-chip trace to work.
Can something be related to this?
