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... Michael Williamson

03:58 AM Software Development: RE: Using the EMIFA interface on the Mitydsp-1810

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

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 Whitney

09:38 AM FPGA Development: RE: FPGA load causes reboot

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

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... Scott Whitney

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... Michael Williamson

03:15 PM FPGA Development: RE: FPGA load causes reboot

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

01:14 PM FPGA Development: RE: FPGA load causes reboot

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

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 ... Michael Williamson

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. ... Scott Whitney
