MW 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 that in the bitstream generation options you are setting all unused I/O pins to "float"? By default they are pulled do...

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"
U-Boot > se...

MW 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 just initialized when you do the following nand read.e?
I would see how fast the unit boots without running the fill. ...

AS 08:14 AM Software Development: NAND Flash reading problem
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 ...

MF 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
