OMAP-L138: Boot issues from NAND Flash on 8bit bus.

Part Number: OMAP-L138

Hello forum

Our company developed years ago a measuring device based on OMAP-L138 where the main system memory is a 8bit bus 1Gbit NAND flash. This system has a serial Flash to boot, and the used NAND flash is Micron MT29F1G08ABADAWP IT.

Lately we modified this project and developed a simpler version. On this new device we removed the Serial Flash, and the board should boot from the NAND. The used memory on the new board is Micron MT29F1G08ABAEAH4:E.

The issue we are facing that we cannot boot from the NAND in the new board. Modifiying the eraly board in the same condition as the new one (removing the Serial Flash, setting the BOOT jumpers in the approrpiate way, ect) the old board boot properly from the NAND flash.

Somebody faced similar issue? We notice the "Faeture set" difference between the 2 NAND's, the old board mounts a NAND with Feature Set = D, and the new one uses a NAND with Feature Set = E. Can be this and issue? In the NAND flash datsheet we cannot find any explanation on this.

Hi Zoltan,

Do you run Linux or RTOS on OMAP-L138?

Hi Bin

I'm working with Zoltan on this project.

It's a Linux.

Hello Zoltan & Oleksii,

I do see a good number of e2e threads popping up on the forums when I search for OMAP-L138 and NAND. Have you taken a look to see if any of those previous threads are helpful?

I usually do a site search on google like this:
site:e2e.ti.com OMAP-L138 NAND

Unfortunately the last OMAP-L138 Linux SDK is getting old enough that we can no longer really offer support on the software.

Regards,

Nick

Yes, I read all other topics related to the boot issues from NAND flash, but nothing similar as our case.

Hello Zoltan,

We are going to be limited in the support we can offer in that case.

I would start by talking with Micron to understand what the difference between NAND with Feature Set = D & E. That could give you a clue, like if the NANDs need to be set up differently.

Regards,

Nick

Agree... In fact I'm looking for FAE contact to be able to understandt the difference between the two feature sets. I will keep updated here the situation.

Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
