I've attached an example boot log using the 2018 April MDK kernel, u-boot, and filesystem on our devkit.

Ok, we shall use O=$PWD/srini_mityarm.
We have deleted srini_mityarm before our build. Hope the logs I have shared does not have any sideeffect becasue of this.

Some unrelated while I look into this:
> O=srini_mityarm
Note, I've found that when doing O= builds, its more reliable if I give it a absolute path. Some projects will create multiple srini_mityarm folders otherwise. So I usually... Jonathan Cormier

Hi,
As per your suggestion, we have used mityarm u-boot and kernel and followed below steps:
*Setup the MDK*++

Thank you for the detailed summary. But I am a little confused at why you did all this work. We provide a working u-boot and kernel which we've modified from the TI's SDK to work with our SOMs. My recommendation would be use them as a... Jonathan Cormier

Marcin,
If you are using a Critical Link product in your design we are happy to help in this forum. From your comments, it looks like you are not using a Critical Link product. Our U-Boot is customized for our specific SOM. I would no... Bob Duke

MG 06:35 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: NAND Flash

This is not SOM. But our module, similar to the MityDSP-L138 only with one memory (NAND) and we use the U-Boot 2009.11.
I am looking for information about what may be the cause of wrong ECC calculation. Can I path this u-boot or use... Marcin Grzelak

JC 03:47 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: NAND Flash

Could you provide all the information on the barcode located on the module? Serial number, model number, etc.
It looks like you have a custom version of the UBL and u-boot.
Some oddities are that your clocks are non standard. U-b... Jonathan Cormier

Hello,
I have a board based on MityDSP-L138 with 4 Gb NAND Flash (MT29F4G08ABADAWP). And I use MityDSP-L138 u-boot (U-Boot 2009.11). But I probably have problem with ECC calculation. After some time during booting I get message: Marcin Grzelak

To use a peripheral on the L138 you need to ensure the pinmux is set correctly and the appropriate driver is enabled.
UART2 is already setup in the kernel for use as an RS-485 port (though without the ... Jonathan Cormier

I'd like to use MitydspL138F Expansion port to get another serial connection to be used by Linux application.
What should be done for this (at U-boot, kernel, etc)?
