T4240: Cannot change to alternative flash boot section

[hum]

Hello,

we have a T4240RDB board, on which we would like to update U-Boot. Currently there is a QorIQ SDK v1.5 U-Boot installed. We flashed a new SDK v2.0 U-Boot to the alternative boot section. When issued an "qix altbank" command to change to the altenative boot section command nothing happens (see log below). Changes to the board's SW3 DIP switch also has no effect. Always the SDK v1.5 U-Boot gets booted.

Has anyone an idea, how to change to the alternative U-Boot ?

Hello Yiping,

changing the SW3 switch settings does not seem to have an effect of changing the boot loader.

We did not yet reprogram anything on the board. We do now want to make an update (mainly of the FMan microcode), but I'm not comfortable programming something in the flash without having a backup to boot from.

The U-Boot also does not know the cpld command.

=> cpld
Unknown command 'cpld' - try 'help'
=> help cpld
Unknown command 'cpld' - try 'help' without arguments for list of all known commands

Hello Manuel Huber,

I just checked our internal database, please refer to the following.

For T4240RDB, the feature of booting from alternative NOR flash bank is supported since SDK 1.7 release.

In T4240RDB User Guide, you can search for "fbank_sel" to see the support for splitting the NOR flash into tow logical halves. The support for fbank_sel is first available on Rev D boards.

So this feature requires revision D of the T4240RDB.

Have a great day,
Yiping

Hello Yiping,

Even we are trying the same here at our lab. We have a T4240RDB QorIQ SDK v1.5 U-Boot installed. Now we see that the flash map has changed between SDK 1.5 and SDK 2.0. 

Now how do we upgrade the flash map to that of SDK2.0.

Thanks,
Sareena.

Hello Yiping,

The board we have here T4240RDB Rev 2.0 Silicon. How do we know if it is the revision D??

Also in case, it is not revision D, what is the way out to program the SDK 2.0 binaries.

Thanks,

Sareena.

Hello Yiping,

My uboot log is as given below. Does it mean that I have revision E??

No, the E in T4240E indicates the chip variant that contains a crypto unit.

Dear Scott,

Thank you for the reply.

1) Where can I find the REV of my T4240RDB board?

2) How to program the SDK 2.0 binaries into the T4240RDB that had SDK 1.5 uboot. Can you give me a brief as to how to go about the flash map change.

If needed I can post it as a new question.

Thanks,
Sareena.

Dear Sareena, 

Did you ever find an answer to this question?

I'm in the same struggles using a T4240E QDS board

Best,

Jakob

Hello Manuel Huber,

For board revision T4240RDB-PD, the NOR flash can be split into two logical halves by setting the FBANK_SEL signal. The FBANK_SEL signal is controlled by setting SW3[3].

As normal, users could use "cpld reset altbank" to change to the alternate bank, but I am confusing now, there is no CPLD version information displayed in the u-boot log, did you program CPLD previsously?

Thanks,

Yiping
