08:57 AM Software Development: RE: Using the EMIFA interface on the Mitydsp-1810
We changed chip select to CS4 and kept having the same issues. We've done some other measurements and tests and we no... Mattias Ekstrom
07:39 AM Software Development: RE: Using the EMIFA interface on the Mitydsp-1810
Hi Mattias,
The only chip select used on the EMIFA by default is CS3 (used for the NAND). Our FPGA driver framewo...

Hi,
I was wondering which chip selects are unused by default? What I can see in the u-boot and linux source is tha...

04:37 PM FPGA Development: RE: FPGA load causes reboot
Mike,
Your .bin file loaded up fine. I had the designer look at the build, and he had some IO not constrained corec...

Scott,
My suspicion is that the pins tied to the EMIFA (a chip select line, a wait line, or perhaps the data lines...

03:43 PM FPGA Development: RE: FPGA load causes reboot
Mike,
The arm is idle when it dies. I will post some captured text. It looks like it can't access the flash memory...

03:27 PM FPGA Development: RE: FPGA load causes reboot
Can you post what the ARM console sees when it crashes? You are downloading via JTAG, correct?
Is the ARM running...

Mike,
I had our fpga designer rebuild our smaller (uPP interface) build that we were running the lx16 and retarget i...

Mike,
Thanks for the quick reply. this is the only lx45 board in house now. I think we are expecting a few more to...

01:04 PM FPGA Development: RE: FPGA load causes reboot
Hi Scott,
Have you confirmed your image works on other MityDSP-L138F with lx56 FPGA modules or is this a new FPGA ...

12:58 PM FPGA Development: FPGA load causes reboot
Hello,
We just got a new mityDSP l138 with the lx45 FPGA. When I try downloading my fpga build via jtag it fails. ...
