- SH 01:30 PM MityDSP-L138 (ARM9 Based Platforms) FPGA Development: RE: JFFS2 driver errors
- Thanks for those suggestions, Mike. According to Table 11-2, the default priority for EDMA is 0 (highest) and for ARM instruction and data is 2 (lower). When I look at these registers in debug mode (DSP), I see these default priorities...

Is the DMA priority configured higher than the ARM data access priority in the Master Priority Configuration registers (see the OMAP-L138 Technical Reference Manual regarding DMA bus mastering priority)?

Perhaps the project was corrupted when you upgraded it to the 13.1 tools. I've attached a copy of the project that has been successfully upgraded to build in the 13.1 tools.
Let us know if you have any issues.

FPGA Development: RE: Quartus II Subscription Edition Error
- Hi Greg,
I am using 13.1 Quartus, and I ran the script that you recommended and the error that I sent you was what I got after I ran the script. So it's not from the compiling part, but just the script.
Thanks!

Are those the same errors you were receiving before? And typically when Quartus reports an error there is a plus symbol next to it that you can use to expand the error message and get more details. Could you provide us with ... -

What version of the Quartus tools are you using?
That project was built with the 13.0 sp1 tools. If you've updated it to the 13.1 tools you probably need to run the hps_sdram_p0_pin_assignments.tcl. Select Tools -> Tcl Sc... - MW 07:14 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Compiling the HelloWorld application with CGT
- You should dump out the full build texts between the two operations and compare.
I suspect that the memory configuration templates (which define the shared regions for DSPLINK) are somehow not the same between the 2 builds.

You need to be careful with the pin assignments.
