Hi, On our OMAP3530 based custom board we are trying to generate Clock on MCBSP with 2700bps data rate.But we were unable to do it after gone through details of the clock source for MCBSP. Can we generate the clock for that data rate (2.7KHz) with MCBSP?
Now we are generating clock on GPIO pins based on the timer tick.I'm attaching the source file
timer_test.c is the code for toggling gpio for 2700Hz
timer_app.c is the user space application to enable timer.
we are facing problem with clock jitter. it is varying between 2695HZ and 2710HZ. We are looking exact 2700HZ clock on our application.
My clock tree is
SystemClock = 19.2 MHz
DPLL_MULT_VALUE = 242
DPLL_DIV_VALUE = 13
CORE_DPLL_CLK = 663.771 MHz
CORE_CLK = 331.8855 MHz
L3_CLK = 165.9427 MHz
How can we generate 2700HZ clock with MCBSP5?
Thank You
