Configure the Linux Address for T4240RDB-64B

[vinothkumars]

Hi All,

I am working on T4240RDB. As per document (QORIQ-SDK-2.0-IC-REV0.pdf) I flash the Linux image 0xE8020000. I needs to flash the Linux image to 0XE8000000.

I needs to configure the Linux address, Will you please tell me the which files to configure the Linux Address  ?

This is not possible because RCW must reside at this address - refer to the Linux SDK Documentation:

Submit Form 

Table 1. NOR Flash Memory Map

Thank you Ufedor,

We have two NOR Flash chip So, Address start from 0XE0000000 and RCW hard-coded in this address as per my customer.

I want to know the files to configure the Linux address. I will check and conform from my side. 

Thanks & Regards,

What is the projected NOR Flash subsystem memory map?

Are chip-selects connected to the Flash devices fixed or they can be swapped?

The Linux uImage address is not configured in files.

Ufedor,

Chip Select 0 (CS 0) connected with NOR flash controller.

What is "Linux address"?

[vinothkumars]

Currently Linux Address is, 0xE8020000 which is Linux image flashed. Needs to configure Linux address to 0xE8000000.

This is just Linux.uImage address. It is not configured. It is used in the bootcmd only.

[vinothkumars]

Yes, We configured uImage address in u-boot env bootcmd to boot. But, Linux have base address or starting address right .

What does it mean?

[vinothkumars]

I mentioned the Load Address of uImage.

How your previous message has to be understood:

> Needs to configure Linux address to 0xE8000000.

?

[vinothkumars]

No, Currently Load address is 0xE8020000. I needs to configure/change this address to 0xE8000000 when uImage build.

We are talking about U-Boot uImage binary object which can be programmed anywhere in the boot ROM

The uImage has built-in header containing RAM loading parameters - Data Load Address and Entry Point Address.

The "0xE8020000" is not used inside uImage.

Thank you Ufedor,

If I changed Linux Address in bootcmd.

> This is just Linux.uImage address. It is not configured. It is used in the bootcmd only

Board is not boot, stop in u-boot and provide the "Cannot get kernel Image"

initcall: eff4ecacHit any key to stop autoboot:  0
WARNING: adjusting available memory to 30000000
Wrong Image Format for bootm command
