Thanks Ben.

I checked out in my board and found the part number to be:

S29GL128N90-R2. (128Mb)

Hi all,

I am using Lite5200B board with SPANSION type flash. UBoot code doesn't detect this flash.

Can anyone please help me what are all the changes to be made to configure SPANSION type flash.

SPANSION 64MB flash.

There are many types of Spansion flash. Please provide the part number.

Please format all future e-mail as Plain Text if you want help. Some curmudgeonly people around here get very annoyed if you don't.

regards, Ben

So how shall I proceed next Ben. Where and in which file this configuration is done?

Whenever I trace out which flash is detected, it always gets detects as FLASH_UNKNOWN.

In flash.c file....

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ulong flash_get_size (FPWV *addr, flash_info_t *info) { int i; FPWV* addr2;

/* Write auto select command: read Manufacturer ID */ /* Write auto select command sequence and test FLASH answer */ addr[FLASH_CYCLE1] = (FPW)0x00AA00AA; /* for AMD, Intel ignores this */ addr[FLASH_CYCLE2] = (FPW)0x00550055; /* for AMD, Intel ignores this */ addr[FLASH_CYCLE1] = (FPW)0x00900090; /* selects Intel or AMD */

/* The manufacturer codes are only 1 byte, so just use 1 byte. * This works for any bus width and any FLASH device width. */ udelay(100); switch (addr[0] & 0xff) {

case (uchar)AMD_MANUFACT: info->flash_id = FLASH_MAN_AMD; break;

case (uchar)INTEL_MANUFACT: info->flash_id = FLASH_MAN_INTEL; break;

default: info->flash_id = FLASH_UNKNOWN; info->sector_count = 0; info->size = 0; break; }

OK. That's a good start. This is a very common flash type.

I don't know anything about this board or processor, but there are people here who do. Please elaborate on what you mean by 'U-boot code doesn't detect this flash', and provide details on the steps you've taken to reach this conclusion.

Also, please don't top-post. Post responses directly after the relevant parts of e-mail messages. The previously-mentioned curmudgeons will eat your children if you continue this habit.

It would appear you have something misconfigured in your hardware or u-boot software. We know basically zero about either, so you will have to work the problem with only generic hints from the list.

Start by verifying the chip select to your flash part is being driven properly.

Once you are sure your hardware is driving the flash OK, use u-boot memory read and write commands to send the CFI manufacturer ID commands. When you figure out how to do CFI commands manually so that the flash responds, your misconfiguration of hardware/software should be very obvious.

The following message thread goes into more details, simply substitute u-boot memory read/write commands for BDI configuration read/write commands. http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/31501/focus=31730

Good luck, gvb

Thanks Ben and Jerry I have fixed the my flash issued.

Is there any way to test the EEPROM through Uboot code?

Thanks in advance.

Regards, Yasotha Balan R

Probably. What kind of EEPROM is it?

regards, Ben

I've forgotten what type of CPU you have. As long as there's a driver for the I2C controller and you've enabled I2C support, this is supported.

Ben I am having another issue now.

Here in my board I have two Ethernet ports; So now I have to set two different IP addresses for these ports.

As when the U-Boot prompt comes up we can set the IP address as,

=> set ipaddr 10.128.19.1 => set ethaddr aa:bb:cc:ee:ff:gg

So above setting is valid only for single Ethernet port.

My doubt how to set IP address for another Ethernet port or what is the method to do that?

{How can I set two different IP addresses for these two ports? [Two different IPs Two different GATEWAYs Two different SERVERIPs]}

The network code really only supports one IP address at a time, which will be used by whatever interface that the 'ethact' environment variable points to. What is your use case for setting up more elaborate networking?
