Part Number: SK-AM62

HW : AM62x SKEVM

SW : SDK8.5

Dear TI Expert,

I'm trying to flash the rootfs binary(2.5GB) to eMMC using DFU. However it is always failed at the same percentage as below.

Error value is TIMEOUT.

mmc write failed: -110

#define ETIMEDOUT 110 /* Connection timed out */

Hello JaeWook,
Can we add gpt partition table to eMMC if not done previously?
This can be done @u-boot
software-dl.ti.com/.../UG-Memory.html

Can we retest flashing rootfs.ext4 with USB-DFU after gpt partition table is added to eMMC?

Best,
-Hong

Hi Hong Guan,

Thank for your feedback.

I already added the gpt partition table in previous as below

=> mmc part

Partition Map for MMC device 0 -- Partition Type: EFI

Part Start LBA End LBA Name
Attributes
Type GUID
Partition GUID
1 0x00000022 0x01da3fde "rootfs"
attrs: 0x0000000000000000
type: ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
guid: 731a396e-ea6f-49bc-ac52-3e97f76eb198

And there was no issue when I flashed the tisdk_base_rootfs(about 400MB) binary.

Thanks & Regards,

Jaewook

And there was no issue when I flashed the tisdk_base_rootfs(about 400MB) binary.

My understanding from your last reply is root_fs eMMC flashing worked on your setup.
What had changed since then?

Hi Hong Guan,

There are no change regarding source code and setup environment.

only the size of rootfs file was increased from 400MB to 2.5GB.

Because of that, the area of eMMC was changed.

Thanks & Regards,

Jaewook.

This is HW revison i'm using.

AM62x SKEVM E3.

I saw the same result on the other board of same revision.

Hello Hong Guan,

I found a pattern of eMMC writing failure from this issue.

mmc write failure always occurs when I try to write more than 3 blocks of 0xFF00FF00 data.

I reproduced "mmc write failed" in u-boot prompt as following this.

=> mw 0x80080000 0xFF00FF00 0x800
=> mmc write 0x80080000 0x10000 1

MMC write: dev # 0, block # 65536, count 1 ... 1 blocks written: OK
=> mmc write 0x80080000 0x10000 2

MMC write: dev # 0, block # 65536, count 2 ... 2 blocks written: OK
=> mmc write 0x80080000 0x10000 3

MMC write: dev # 0, block # 65536, count 3 ... mmc write failed
0 blocks written: ERROR

Please check this.

Thanks & Regards,

Jaewook

Hello Hong,

Let me summarize the situation so far.
At first, eMMC write failed when flashing the tisdk-default-image binary.
After debugging, I found that the binary fails if it contains specific data(0xFF00FF00).
And it can be easily reproduced with the same command as above.
The same problem occurred on all 3 boards that our team had.
I expect that you can easily reproduce it too.

Please check this issue.

I think this is a major problem for anyone using the AM62x EVM or SDK.

Thanks&Regards,

Jaewook.

Hello JaeWook,
Will you help re-run the test by replacing "0x80080000" with "${loadaddr}"?

Hello Hong,

Please find below result. it is same as before.
