- 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... - 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"
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. ... - 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.
