Yes, it works (thanks):... Mark Lyon

03:24 PM Software Development: RE: OMAP I2C

Mark,
I probably should have used O_RDWR instead of O_RDONLY. I am surprised it worked with just O_RDONLY.
The ... John Pruitt

03:17 PM Software Development: RE: OMAP I2C

Interesting. We were using Qnx's demo which uses DCMD_I2C_RECV rather than DCMD_I2C_SENDRECV so that was part of the... Mark Lyon

01:27 PM Software Development: RE: OMAP I2C

I am attaching a test program that was used on a board to read the factory config information using i2c0.
The outp... John Pruitt

05:13 PM Software Development: RE: OMAP I2C

Can you try to get the sample program that the qnx engineer used?
Thanks.

09:47 AM Software Development: RE: OMAP I2C

An engineer from QNX hooked a scope to I2C0 lines on their EVM board and sent the sendrecv command. They were able to... Mark Lyon

03:04 PM Software Development: RE: OMAP I2C

IFor what it is worth, it should be noted that the i2c accesses in the startup code and in the i2c_get utility are do... John Pruitt

02:08 PM Software Development: RE: FPGA Driver

I have posted a new BSP which has a fixed FPGA driver and fix to the timer routines so the clock period can be change... John Pruitt

Mark,
I2C0 is not something that needs to be turned on. It is used internally in the startup code to read configur... John Pruitt

09:00 AM Software Development: RE: OMAP I2C

It looks like neither I2C driver is started by default.
We are trying to use I2C0
There is an error generated if we... Mark Lyon

Mark,
The files under /dev/fpga are not intended to be executed. They are intended to be opened and then read from... John Pruitt

02:27 PM Software Development: RE: FPGA Driver

Tried that - now I'm having a very strange, possibly unrelated problem where the files created under /dev/fpga are cr... Mark Lyon

05:04 PM Software Development: RE: FPGA Driver

Mark,
These is a mistake in the fpga driver as provided. It is printing out the virtual addresses for the cores in... John Pruitt

03:35 PM Software Development: RE: FPGA Driver

Understood. I have a memory block in the FPGA that I was able to examine using mmap_device_memory().
The offset wa... Mark Lyon

03:29 PM Software Development: RE: FPGA Driver

Mark,
The 5 fpga device files (cmd, image, state, version, and devices) are for loading an image into the fpga and... John Pruitt

02:51 PM Software Development: RE: FPGA Driver

I have the FPGA driver loaded, with the FPGA mapped into 0x66000000.
If I want to access the FPGA for a user applica... Mark Lyon

03:57 PM Software Development: RE: Pin MUX

Just saw a signal out of the port - thanks. It may have been a conflict with the I2C or something else we tried along... Mark Lyon

03:19 PM Software Development: RE: Pin MUX

Mark,
I have tried using a scope on an INDIO board (80-000268RI-2 rev. B, serial number 110765) with a module (L13... John Pruitt

07:45 AM Software Development: RE: Pin MUX

We are using RS-232 at TTL levels, so that is not a problem.
We had done all the steps you outlined and we are not s... Mark Lyon
