SD Card boot for P4080DS

[appalanaidug]

Hello,

We are trying to prepare a bootable SD Card for P4080DS system. Since the NOR flash in the development system got erased, we are trying to copy the u-boot files from the linux pc(running on VMware) to the SDCard.

The SDCard was partitioned into two - one bootable partition of 512MB (FAT16) and other partition with remaining space on the card.

The following two commands were followed to copy u-boot binary image and  FMan microcode (both obtained from SDK ISO file) to the SDcard.

After execution of these commands, no files are visible on the SDcard.

The SW1 settings on P4080DS were modified to boot from SDCard (set to 00110011).

No output is observed on U-boot console.

Even if the files are manually copied into the card, no output is observed on the U-boot console.

Any help is requested.

Thankyou.

Steps to prepare bootable SD card for the P4080DS:

1) Write U-Boot to SD card (CHECK that  "sdb" corresponds to the SD card in your case):

dd if=u-boot-sdcard-2016.01+fslgit-r0.bin of=/dev/sdb bs=512 seek=8

2) Write FMan microcode to SD card:

dd if=fsl_fman_ucode_p4080_r3.0_106_2_18.bin of=/dev/sdb bs=512 seek=1680

hello,

Thankyou for the help.

On exceuting the above commands, the following is the log 

[root@localhost files]# dd if=u-boot-sdcard-2016.01+fslgit-r0.bin of=/dev/sdb bs=512 seek=8
1632+1 records in
1632+1 records out
835840 bytes (836 kB) copied, 0.0582739 s, 14.3 MB/s
[root@localhost files]# dd if=fsl_fman_ucode_p4080_r3.0_106_2_18.bin of=/dev/sdb bs=512 seek=1680
59+1 records in
59+1 records out
30540 bytes (31 kB) copied, 0.0152906 s, 2.0 MB/s

After mounting the SD Card back, no files are seen on the card.

P4080DS u-boot console also does not show any output.

Few more questions regarding SD Card preparation.

1. My linux pc detects sd card as a physical device and not as SDHC card. Is that the reason why "dd" command does not show any files copies onto the card? ( i can copy files using "cp" command to the card, which are visible on mounting the device)

2. Is there no need to partition the SDcard?

Thankyou in advance

1) Correct.

2) For U-Boot - no need.

What are P4080DS on-board configuration switches settings?

Use "dd" to "copy" first 2MB of the prepared SD card and attach resulting image for inspection.

Hello,

Thank you for the help.

On formatting the SD Card and re-running the above two "dd" commands, I could boot from the SDCard with the following switch settings:

SW1: 00110011

All other switches are default settings as given in the SDK manual

I have attached the U-boot log for reference.

May I know the steps to re-program the NOR flash.

1. What are the different files required to re-program the NOR flash.

2. Commands to program the NOR flash from the U-boot console 

3. How to configure Ethernet ( in case tftp transfer is required, since the U-boot file shows the following errors )

Hello appalanaidug;

I am going through the identical process.  May I ask what file format type did you use when you formatted the SD Card?

Thanks in advance,

Bill
