Re: [Ltib] Ltib - How to make the MAC address in EEPROM works with kernel 2.6.34 just like kernel 2.6.27?

[Mike RA9FTM]

here is the link ftp://ftp.phytec.com/phyCORE-LPC3250%20(PCM-040)/CDL/nxpmcu_lpc32xx_cdl_v20.zip
The code is modified, it now contains support not only phy3250, but also ea3250 board.

Dear Mike,

Well, the latest CDL I got is version 1.22.

Below is the source link:

http://ics.nxp.com/support/software/lpc32xx.cdl.drivers/

You said that they have the v2 released, but I think I do not have the access right to the ftp. It's hard for me to find the latest release. (if the above link is not the latest one. :-( )

My question is just like you. I though it doesn't make sense to remove such important information from EEPROM. So I just want to know the thought of the NXP developers. Maybe the kernel 2.6.34 is just in the beta test stage, the EEPROM is just temporarily empty for developing?

Hi, Henry

They also removed writing MAC adress, SDRAM memory configuration information, board hardware id to the EEPROM in the latest S1L version (CDL library v2 at the phytec ftp).

My question is, how u-boot will know what SDRAM memory is installed on the board?

Yes,

Sorry to forget tell you that it is LPC3250 platform.

Hi

Is your message about lpc3250?

Dear NXP guys,

As a new issue, I create a new topic for this problem.

I have knew the facts as below:

1. The MAC address was read from EEPROM in kernel 2.6.27. 

2. The MAC address was passed by u-boot through kernel parameter in kernel 2.6.34. 

Below is my question:

1) Why the mechanism chaged? Is there any consideration or limitation to make kernel 2.6.34 with EEPROM?

2) Could I make the mechanism in 2.6.34 become the same with kernel 2.6.27? How?

Henry
