Can't boot u-boot from bank 5 on T4240

[sergeissakov]

We have two T4240QDS systems and are seeing this same behavior on both.

We can copy u-boot from bank 1 to bank 4 and then boot successfully from bank 4.

But when we copy u-boot from bank 1 to bank 5 and try to boot from bank 5, the system sits in reset.
Are there boot parameters or something else that has to change in order to use u-boot in bank 5?

Thanks!

Dear Serge Issakov

I need your help.

I have a T4240qds board, too.But when I set u-boot environment variables，I type the wrong information.

Could you help me to check it by typing "printenv" when you boot your board?

My information like this:

bootargs=root=/dev/sda3 rw rootdelay=10 size=30000000 console=ttyS0,115200

bootcmd=ext2load sata 0:3 0x1000000 /boot/uImage; ext2load sata 0:3 0xc00000 /boot/dtb_file;bootm 0x1000000 - c00000

I want to know the correct infomation.

Thank you very much!

Hello Mengtian,

Please check whether this would help youT4240rds boot from sata ssd.

If your problem remains, please create a new thread in QorIQ processor block, you could continue to discuss.

Have a great day,

Dear Yiping Wang,

     I just follow your advice to modify my "env" of Board T4240QDS  fromT4240rds boot from sata ssd.

     But I still failed.Like this:

=> setenv bootcmd 'setenv bootargs root=/dev/sda1 rw console=ttyS0,115200;sata init;ext2load sata 0:1 1000000 /boot/uImage;ext2load sata 0:1 c00000 /boot/uImage-t4240qds.dtb;bootm 1000000 - c00000'

=> saveenv

Hello Mengtian,

Have you also followed other steps to format and deploy images into SATA?

Thanks,

Dear Yiping Wang,

     My board is T4240qds rather than T4240rds,I cannot solve the problem now.

     Could you help me to check it by typing "printenv" when you boot  board T4240qds?

Thanks!

Hello Serge,

Please refer to this document http://cache.freescale.com/files/32bit/doc/user_guide/T4240QDSQSG.pdf?fasp=1&WT_TYPE=Users Guides&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Documentation&fileExt=.pdf

The flash space is further divided into 8 virtual banks. With SW6[1:4] = 0000 the mapping is as follows:

|Bank7 | e8000000 - e8ffffff

|Bank6 | e9000000 - e9ffffff

|Bank5 | ea000000 - eaffffff

|Bank4 | eb000000 - ebffffff

|Bank3 | ec000000 - ecffffff

|Bank2 | ed000000 - edffffff

|Bank1 | ee000000 - eeffffff

|Bank0 | ef000000 - efffffff

The default SW6[1:4] = 0000, u-boot is at 0xEFF40000(bank0), RCW is at 0xE8000000 (bank 7), the alternate u-boot is at 0xEBF40000(bank4), alternate RCW is at 0xEC000000(bank3).

Please make sure you have deployed u-boot image and RCW appropriately, assume your switch setting is also SW6[1:4] = 0000.

u-boot is at 0xEAF4000000(bank5), RCW is 0xEB000000(bank4).

Then change SW6[1:4] to bank 5, and boot the system.

U-boot is always at 0xeff80000.

If your problem remains, please describe your procedure in details.

Have a great day,
Yiping
