08:57 AM ARM9 Based QNX Platforms Software Development: DSP/BIOS dsplink for QNX
Has anyone gotten DSPlink running under QNX for the MityDSP? I see that you have set the DSPlink memory base address ...

09:46 AM ARM9 Based QNX Platforms Software Development: RE: NAND Flash Driver Crashes
No joy. When I try to erase (or just load) it, I get a whole bunch of BADBLK errors:
fs-etfs-mitydsp-omapl1xx: read...

Yes, it works (thanks):...
03:17 PM ARM9 Based QNX Platforms 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...

09:47 AM ARM9 Based QNX Platforms 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...

09:00 AM ARM9 Based QNX Platforms 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...

03:35 PM ARM9 Based QNX Platforms 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...
