09:27 AM Software Development: RE: NAND Flash reading problem

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

07:27 AM Software Development: RE: NAND Flash reading problem

And of course, one workaround might be to load the ARM application into memory from NAND first, then configure the FP... Michael Williamson

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 prob... Michael Williamson

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 tr... Ahmed Shaaban

07:11 AM Software Development: RE: NAND Flash reading problem

Hi Ahmed,
Sounds like the loaded FPGA is causing NAND read issues? Have you checked your FPGA image and made sure... Michael Williamson

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 fol... Ahmed Shaaban

09:20 AM Software Development: RE: NAND Flash reading problem

Why are you running "mw.b 0xc2000000 0xFF 0x400000" as part of your load? You are going to overwrite that RAM you ju... Michael Williamson

Hi everyone,
I'm working on MityARM 1808F.
I have two images: SYS/BIOS image and FPGA image. After some suggestions... Ahmed Shaaban

10:01 AM Software Development: RE: Real time SATA writes

This problem was resolved by using a SLC SSD drive instead of MLC. The write times on the SLC are much lower. Mary Frantz
