AM3358: NAND not detected on GP EVM

Part Number: AM3358
Other Parts Discussed in Thread: TMDXEVM3358

Hello, TI Experts,

We have a question about NAND-Flash on TMDXEVM3358.

We create SD-card by create-sdcard.sh of PROCESSOR-SDK-LINUX-AM335X.

And we tried to boot from the inserted SD card on TMDXEVM3358.

Then we found the message "NAND: 0 MiB" like below;

>U-Boot 2017.01-00319-g7752743-dirty (Oct 10 2017 - 14:14:36 +0900)

>CPU : AM335X-GP rev 1.0

>Model: TI AM335x EVM

>DRAM: 512 MiB

>NAND: 0 MiB

>MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1

Question:　

　Is there same experience?

We would appreciate if you tell us how to solve this problem.

I would also attach "pdf" the DIP-SW setting as below;

Profile[3:0]=0000

BOOT[4:0]=10011

Hi,

Besides setting the SYSBOOT switched you also need to set the Profile switch. See processors.wiki.ti.com/.../AM335x_General_Purpose_EVM_HW_User_Guide CPLD profiles can be seen here: processors.wiki.ti.com/.../Am335x_gpevm_pinuse.zip NAND is available in all profiles, except #2 and #3.

Hi,

Thank you for your prompt reply.
I have also same understanding with you.
So I set the Profile switch to #0 to use NAND.

From your information, the Profile switch seems to be set properly to use NAND.

We would appreciate to continue to investigate the problem.

OK, I'm transferring this to the software team. They will continue from here.

Hello matusan,

I set the exact DIP-SW settings like you and NAND size got detected by U-Boot. Seems like you have something modified in your U-Boot. Can you try to boot with the prebuilt images from Processor SDK?

Best regards,
Kemal

Hi,

Thank you very much for your kindness.

I really appreciate your help.

From your information,

I can understand you found NAND size got detected by U-Boot on TMDXEVM3358.

I got another TMDXEVM3358 and tried to boot with the prebuilt images from Processor SDK.

But result was same. (we found the message "NAND: 0 MiB" on both two TMDXEVM3358.)

Question:

Are there any difference from your experience of U-Boot on TMDXEVM3358 as below?

(Do you find any key difference from your EVM and our EVMs of attached pdf?)

- Both two EVM versions (from teraterm console message)

1) CPU:AM335X-GP rev 1.0

2) CPU:AM335X-GP rev 2.1

- Both EVM don't have U9(NAND device on the CPU Board) like attached pdf.

but

Both EVM have U5(NAND device on the Daughter Board).

We would appreciate if you tell us how to use U5(NAND device on the Daughter Board).

Best regards,

Our hardware configuration is exactly the same as yours.

Can you test my scenario on your board. Copy the attached https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/5140.MLO and https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/u_2D00_boot.img to SD card.

nand erase.chip
mmc rescan
fatload mmc 0 0x82000000 MLO
nand write 0x82000000 NAND.SPL
fatload mmc 0 0x82000000 u-boot.img
nand write 0x82000000 NAND.u-boot

Then reboot and check the result.

Hi,

Thank you very much for providing us your MLO & img files.

I really appreciate your help.

I tried to boot with your files and send the result with attached pdf.

Unfortunately, result seemed to be same.

(we found the message "NAND: 0 MiB" on both two TMDXEVM3358.)

If you have any clue, please tell us.

Best regards,

Can you turn on/off the board after switching and check if the NAND will be detected in other profiles #1, #4, #5, #6, #7?

Hi,

I found success to boot from NAND with your guide and files.

Thank you very much.

// Daughter board connection seemed to have problem.

// So I re-built it with CPU board tightly.

But I found another problem.

If I tried to boot from NAND with prebuild files (MLO & u-boot.img) of PROCESSOR-SDK-LINUX-AM335X 04_00_00_04

following your guide as below, NAND boot seems to be fail. (there are no text on teraterm window).

nand erase.chip

mmc rescan

fatload mmc 0 0x82000000 MLO

nand write 0x82000000 NAND.SPL

fatload mmc 0 0x82000000 u-boot.img

nand write 0x82000000 NAND.u-boot

Question:

Could you tell us the difference between your files(MLO & u-boot.img) and prebuild files?

Best regards,

In my previous post I have attached the prebuilt images from the latest PROCESSOR-SDK-LINUX-AM335X 04_01_00_06. I have just tried to boot with the prebuilt images from PROCESSOR-SDK-LINUX-AM335X 04_00_00_04 and I succeeded again.

Hi,

I found success to boot from NAND with the prebuilt images(MLO&u-boot.img) from PROCESSOR-SDK-LINUX-AM335X 04_00_00_04.

Thank you very much.

Now, I tried to Linux-kernel boot from NAND as following procedures on the EVM(target).

U-Boot# setenv ipaddr 192.168.0.6

U-Boot# setenv serverip 192.168.0.1

U-Boot# nand erase.chip

U-Boot# mw.b 0x81000000 0xFF 0x2950000

U-Boot# tftp 0x81000000 MLO-am335x-evm

U-Boot# cp.b 0x81000000 0x81020000 20000

　　　　cp.b 0x81000000 0x81040000 20000

　　　　cp.b 0x81000000 0x81060000 20000

U-Boot# tftp 0x81080000 am335x-evm.dtb

U-Boot# tftp 0x810c0000 u-boot-am335x-evm.img

U-Boot# tftp 0x81200000 zImage-am335x-evm.bin

U-Boot# tftp 0x81a00000 arago-base-tisdk-image-am335x-evm.ubi

U-Boot# nand write 0x81000000 0x0 0x2950000

then reboot & "run nandboot"

But error of "Kernel panic" is occurred such as attached txt-file as below.

Is there anything missing?

We would appreciate if you tell us recommended way of Linux-Kernel boot from NAND.

You are not writing the complete arago-base-tisdk-image-am335x-evm.ubi, you are writing 41Mib out of 145Mib. Its size has increased during the SDK development. Change the 0x2950000 to 0x92c0000.

Hi,

I found success to boot Linux from NAND.

Thank you very much.

Our customer want to know Linux-booting from NAND automatically.

We would appreciate if you tell us recommended way of Linux-booting from NAND automatically.(without typing "run nandboot")

Best regards,

=> setenv bootcmd run nandboot
=> saveenv
Command will do the trick.
But after the saveenv you can see :
Saving Environment to FAT...
writing uboot.env
done
That means the environment is saved to SD card.
To save the environment to NAND you must define #define CONFIG_ENV_IS_IN_NAND in <Processor SDK>/board-support/u-boot-<version>/include/configs/am335x_evm.h and recompile the U-Boot (make u-boot from the top Processor SDK directory).
Then you should see that message while the environment is saving to NAND:
=> saveenv
Saving Environment to NAND...
Erasing redundant NAND...
Erasing at 0x1e0000 -- 100% complete.
Writing to redundant NAND... OK
=> saveenv
Saving Environment to NAND...
Erasing NAND...
Erasing at 0x1c0000 -- 100% complete.
Writing to NAND... OK

Hi,

I found success to boot Linux from NAND automatically.(without typing "run nandboot")

Thank you very much. (Your explanation is excellent!)

I will guide to the customer as following procedure.

1: Edit "am335x_evm.h"

　　add -> #define CONFIG_ENV_IS_IN_NAND

　　delete -> #define CONFIG_ENV_IS_IN_FAT

2: Rebuild u-boot & copy to SD card.

(I also checked NAND related configure in .config file as below.)

　　　- CONFIG_SPL_NAND_SUPPORT=y

　　　- CONFIG_NAND_BOOT=y

3: Boot from SD-card & type commands to write u-boot.img to NAND.
