- Matt,
The mityomapl138 repo was never made public. However the source is included in the MDK. The mityomapl138 path should be equivalent to /home/mitydsp/MDK_2014-01-13/sw/.
I attempted to create a patch to use the local copy of ...

Is there a work around for this problem? I am experiencing the same problem as well.

- You are right one of the EMIFA pins was used as a FPGA IO, after replacing this pin everything works as expected.
Thanks Mike.

- And of course, one workaround might be to load the ARM application into memory from NAND first, then configure the FPGA, then launch the ARM app.
The only thing is that is there is contention on the EMIFA bus you should figure out whe... - MW 07:26 AM Software Development: RE: NAND Flash reading problem
- If the FPGA is loading properly and you are floating the unused pins, then the bitstream generation settings are probably OK.
Are you using the EMIFA framework we provide in the BSP or your own? You might drop a chipscope in and watc... - AS 07:21 AM Software Development: RE: NAND Flash reading problem
- Hi Mike,
I had made what you said (sets all unused I/O pins to float), but I still have the same problem.
I have tried the "IndustrialIO.bin" FPGA image (instead of my image) and everything works fine (FPGA loaded with "IndustrialIO" a...

- Hi Ahmed,
Sounds like the loaded FPGA is causing NAND read issues? Have you checked your FPGA image and made sure that in the bitstream generation options you are setting all unused I/O pins to "float"? By default they are pulled do... - AS 06:33 AM Software Development: RE: NAND Flash reading problem
- Thanks Mike,
you are right i don't have to overwrite RAM contents so I modified the u-boot commands to be as the following:
U-Boot > setenv progfpga "sf probe 0; sf read 0xC0700000 0x580000 0x40000; loadfpga 0xC0700000"

- Why are you running "mw.b 0xc2000000 0xFF 0x400000" as part of your load? You are going to overwrite that RAM you just initialized when you do the following nand read.e?
I would see how fast the unit boots without running the fill. ... - Hi everyone,
I'm working on MityARM 1808F.
I have two images: SYS/BIOS image and FPGA image. After some suggestions from " Alexander Block" and " Michael Williamson" over a year ago, I used to use NOR Flash for FPGA Image and the NAND ...
