Other Parts Discussed in Thread: AM3358
Hello,
I'm developing a firmware for the PRUs of am3358 from Sitara SoC. I'm using the Beagle Bone Black with a JTAG-Header, Code Composer Studio v10 and the PRUC-Compiler 2.3.3. I'm debugging bare-metal, without linux running, with the XDS110 Debug-Probe.
I need to read a GPI-Pin with a frequency of 3 MHz and do another operations in the meantime - what is the best way to do this?
Is there a possibility to set up a timer-interrupt (as known form ARM-Processors) that will fire up when the Timer Counter is bigger than Compare Value (I thought about using the IEP-Timer for this), interrupt other operations if needed and start an interrupt handler? Or is there some other way to handle this?
I also looked at the example for the IEP-Timer from the pru support package (PRU_IEP.c). When I run this code it got stuck in the while-loop (line 79) - I concluded, that the interrupt was not forwarded from INTC to the Bit 31 of R31. I enabled the Host0, system interrupt number 7 and global host interrupt (in HIER, ESR0 and GER register), but it still didn't work. Could you help me getting it to run?
Thank you in advance for your help,
Aneta
