Hi Lenny. Sorry for the delay.
Usually, PRU1 will have new data received from the ARM before PRU0 complete
one PWM sample, this is the key point. If the ARM sporadically could not
deliver a control action in time, the PWM should just repeat the last
values, so reading the old data is desirable.

Yes, i2cdetect should detect the camera. The C code in host/ov7670-i2c.c

But there are important prerequisites for the OV7670 I2C communication:

- Pulse the RESET line and leave it set to VCC.

So if you have the dtb for Angstrom, it should be decompilable.

Yeah, I saw that post. I've also emailed them for support. I could try to fix
it myself, but despite much time invested, I just don't "get" DTBs (and I've

boards around a lot of different MCUs). Their

Oh sorry, I didn't see your PS ;)
In case that one PRU reads from the scratchpad and in the same cycle the
other PRU writes to it, I am pretty sure that there will be no conflicts.
It is the standard behaviour when you program sequential logic with a
hardware description language. However, the

have you looked at the PruReferenceGuide section 5.2.4.2 (p.34-35)? Let me

A collision occurs when two XOUT commands simultaneously access the same

Table 20 shows the priority assigned to each operation when a collision
occurs. In direct connec

However, at this time my application was intensivly working with the serial

through my application.

Thank you Robert for the fast response.
I assume,I should use your instructions on a Linux-PC and not on the BBB?
Normally I only work with Windows, but I think I will find a virtual machine to
perform your suggested steps.
