- My mistake... misstyped MLO load addresses (0x4000 instead of 0x40000).
Started over an loaded everything from the UART boot. Successfully. - JC 10:03 AM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: Create ubifs

Go figure. Glad you got it working. If your going to be flashing a bunch of units over UART, you may want to update... - JC 09:58 AM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: Create ubifs
- Ran the same commands on our board and was able to boot from nand. Note that I didn't boot from UART but this shouldn't matter.
I started from a newer u-boot version but there doesn't appear to be any relevant changes between your ver... - MF 09:48 AM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: Create ubifs

- See attached console log file.
Yes. I did the following: - JC 08:58 AM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: Create ubifs
- Right, I forgot that they were inverted.
I'm not seeing anything wrong in what you posted, could you provide the console log when you program it?
Also when you rebuilt u-boot did you use the mityarm335x_4kpage config? - MF 08:53 AM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: Create ubifs
- From that page:

- Try the boot cfg mentioned here: https://support.criticallink.com/redmine/projects/armc8-platforms/wiki/UBIFS_Nand_Boot#Boot-Config-Pins
- MF 02:08 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: Create ubifs
- I recompiled mtd-utils and made a ubi.img.
Also recompiled u-boot to get u-boot-spl.bin from u-boot-2013.10
Booted over UART, loaded u-boot-spl.bin, loaded u-boot.img and booted u-boot.
So far, so good.
Loaded NAND as follows...

- Here is a copy of instructions from the 1GB part. I'm going to copy it for the other parts as well.

- I downloaded the base rfs from the Files tab. Ran the following:

- Hi Mary,
The exported root filesystem is the contents of the rootfs partition on your SD card. If you mount your SD on a Linux host, you can archive that partition using tar: - I need to create a ubifs. Our product will not have a SD card interface, so first article booting will have to be over UART. I understand how to load MLO, U-boot, and the kernel image into NAND.
I have the EVM board: 3354-GX-X38RC

- You are right one of the EMIFA pins was used as a FPGA IO, after replacing this pin everything works as expected.
Thanks Mike.
- MW 07:27 AM MityDSP-L138 (ARM9 Based Platforms) 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 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 MityDSP-L138 (ARM9 Based Platforms) 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 MityDSP-L138 (ARM9 Based Platforms) 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... - AS 07:13 AM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: MityARM - ECC: uncorrectable

- 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 MityDSP-L138 (ARM9 Based Platforms) 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...

- 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 MityDSP-L138 (ARM9 Based Platforms) 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.

- Which module do you have?
What u-boot version are you using? Can you provide the bootlog from power on till you get into u-boot? - Hi,
I have a MityARM card.
I try to flash the NAND memory according to the guidelines that are given for the MitySOM, "here":https://support.criticallink.com/redmine/projects/armc8-platforms/wiki/UBIFS_Nand_Boot#256MB-NAND. My writ...
