How to make a bootable SD card with u-boot on the P2020RDB ?

[david-xia]

under the  ubuntu : how  to  make  a bootable SD card with u-boot  on the  P2020RDB ?

[yipingwang]

Hello Wei Xia,

For Non-PBL platforms, you need to use boot-format application to write u-boot to SD card.

Please refer to the document System Boot from SD/MMC Card with SDK 1.6 images created by me.

Have a great day,

Hello Wei xia,

This document is for SDK 1.6, for SDK 1.2 the boot format configuration file is different, it should be config_ddr3_1gb_64bit_p2020rdb_pc.dat according to README file in boot_format source.

Please use ~/SDK/Target_Images/E500V2_Images/P2020RDB$ /home/freescale/SDK/QorIQ-SDK-V1.2-20120614-yocto/build_p2041rdb_release/tmp/sysroots/i686-linux/usr/bin/boot_format /home/freescale/SDK/QorIQ-SDK-V1.2-20120614-yocto/build_p2041rdb_release/tmp/sysroots/i686-linux/share/boot_format/config_ddr3_1gb_64bit_p2020rdb_pc.dat  u-boot-sd-P2020RDB-PC_SDCARD-git-r17.bin -sd /dev/sdb

Please note -sd should be specified a device name not a partition name.

Have a great day,
Yiping

Hello Wei Xia,

Please note there is a space between "-sd" and "/dev/sdb", you omitted it in your command line.

In addition, I don't have SDK 1.2 source code, please check whether "/home/freescale/SDK/QorIQ-SDK-V1.2-20120614-yocto/build_p2041rdb_release/tmp/sysroots/i686-linux/usr/share/boot_format/config_ddr3_1gb_64bit_p2020rdb_pc.dat" exist.

If it doesn't exist , please use the following method to get the config date file information.

Please refer to README in build_p2020rdb_release/tmp/work/ppce500v2-fsl-linux-gnuspe/boot-format/git-r0/git folder to get configuration file name for P2020RDB-PC.

Please note there should be no "." before "/home/freescale/SDK/QorIQ-SDK-V1.2-20120614-yocto/build_p2041rdb_release/tmp/sysroots/i686-linux/usr/share/boot_format/config_ddr3_1gb_64bit_p2020rdb_pc.dat" in your command line.

Have a great day,
Yiping

Hello Wei Xia,

The application boot_format should print this kind of information.

In the log, have you got the following information.

"Congratulations! Completed successfully."

As I mentioned previously, please make sure the configuration data file is the same as address in README file.

If your problem remains, please provide the whole boot-format log to me.

Have a great day,
Yiping

Hello Yiping Wang,

The boot_format is ok. but the SD card is empty. nothing in the SD card.

Hello Wei Xia,

Before using boot-format to write u-boot to SD, it's better to format the first partition to accommodate u-boot.

# mkfs.vfat /dev/sdb1

How do you know the SD is empty? Would you please provide SD raw data of the beginning section?

Your SD device is named /dev/sdb, right? It 's difficult to guess the probable cause.

Have a great day,
Yiping

OK.

Congratulations! It is done successfully.

The boot_format tool seems to report a successful write to the SD card, after which I unmount from my Linux machine. I then ensure that the P2020RDB attempts to pull u-boot from the SD card , plug the SD card into my P2020RDB, and power up. Based on all the documents I've read this should be enough, but the only response I receive from the P2020RDB is asleep-led light. The serial console I have connected to the P2020RDB via UART0 does not produce any output that I could use to help diagnose the problem.

My question to the community is: Is the board completely bricked? Or is there something I'm doing wrong in the SD card formatting.

Pertinent configuration details:

Workstation: Ubuntu 14.04

QorIQ SDK: 1.2

SD Card: 1GB SDHC

Many thanks for your assistance.

Hello Wei Xia,

About your P2020RDB board, is it P2020RDB-PC or P2020RDB-PCA? Would you please help to take a photo to help me to make confirmation if necessary?

In addition, have you changed the switch setting to SD boot? You could refer to the SDK document in the ISO.

Thanks,

Yiping

Hello Yiping,

Our design is reference to the following P2020E RDB. we replaced the DDR2 for DDR3.

I have changed the switch setting to SD boot‍.

Thank you very much!

[yipingwang]

Hello Wei Xia,

Please note the boot format data file config_ddr3_1gb_64bit_p2020rdb_pc.dat is for P2020RDB-PC demo board, if you are designing new board with new DDR, you need to modify the DDR controller configuration parameters in the configuration file.

Boot format application writes the header to SD according the .dat file, after the board setup, the DDR controller will be configured according to the header in SD, then u-boot could be copied to DDR.

so you need to do:

1. Calculate DDR controller configuration parameters according to your DDR data sheet. Freescale provide QCS tool could assists you to do this.

2. Modify DDR controller parameters section in the .dat file, you could refer to P2020 reference manual for detailed information about SD header.

Have a great day,
Yiping

Hello Yipng,

Can you send me QCS tool of the latest version of the dowload link?

Thanks!

[yipingwang]

Hello Wei Xia,

I provide another method probably you could try to use boot u-boot in SRAM instead of DDR, if you feel difficult to configure the DDR controller, you could refer to P2020DS for an example.

1. Modify include/configs/P1_P2_RDB.h as include/configs/P2020DS.h.

#ifdef CONFIG_SDCARD

#define CONFIG_SYS_RAMBOOT

#define CONFIG_SYS_EXTRA_ENV_RELOC

#define CONFIG_SYS_TEXT_BASE            0xf8f80000

#define CONFIG_RESET_VECTOR_ADDRESS    0xf8fffffc

#endif

2. Modify boot-format configure file based on config_sram_p2020ds.dat.

Have a great day,

Hello Yiping,

"Ensure that cfg_rom_loc[0:3] (Boot_Rom_Loc) are driven with a value of 0b0111." ——

In jump line configuration under the condition of startup for SD card,the meaning of this

sentence is to keep for a while after the local reset this value or keep this value?

Now our development board waveform output SD_CLK no clock.

Thanks!
