Loading file from USB storage in u-boot
Overview
This document talks about how we can load files on USB memory stick, into system RAM from u-boot. Here we take ADSP-SC573 board as example.
Hardware Setup
- An ADSP-SC5xx EZ-Board:
- ADSP-SC589 Ezkit v1.1 and above, or,
- ADSP-SC584 Ezkit v1.0 and above, or,
- ADSP-SC573 Ezkit v1.2 (BOM 1.8) and above
- A USB memory stick
- A USB adapter cable (provided in the ezkit box)
Connect USB stick to the USB OTG port, via the USB adapter cable, as following, and reset the board
Test method
Formatting the USB stick
Insert the USB memory stick into a Linux PC, you will see new items show up in /dev/sd*, as following:
$ ls /dev/sd* /dev/sda /dev/sda1 /dev/sda2 /dev/sda5 /dev/sdb /dev/sdb1
In this case the /dev/sdb is for the USB stick we just plugged in.
Caution : Please double check the device node newly created for your memory stick, otherwise serious damage like system permanent crash down happens!
The format a vfat partiton on it:
$ sudo mkfs.vfat /dev/sdb1 [sudo] password for ... mkfs.vfat 3.0.12 (29 Oct 2011)
Copy files in it
$ sudo mount /dev/sdb1 /mnt $ cd build/tmp/deploy/images/adsp-sc573-ezkit $ sudo cp zImage /mnt/zImage $ sudo cp adsp-sc5xx-ramdisk-adsp-sc573-ezkit.cpio.gz.u-boot /mnt/ramdisk.cpio.gz.u-boot $ sudo cp sc573-ezkit.dtb /mnt $ sudo umount /mnt
Then plug the USB stick to the USB OTG port in board, via the USB adapter cable, and reset the board
Start the USB
Run “start usb” In the u-boot console:
sc # usb start (Re)start USB... USB0: scanning bus 0 for devices... 1 USB Device(s) found scanning usb for storage devices... 1 Storage Device(s) found
Run “fatls usb 0:1” In the u-boot console:
sc # fatls usb 0:1 12452384 zImage 10306 sc573-ezkit.dtb 2 file(s), 0 dir(s)
This shows the FAT files information in USB device 0 partition 1, with files we copied.
Load file into RAM
As example we load both the dtb, zImage and the ramdisk file into proper location.
Don't forget to change the file/dtb name and load address according to your board type (i.e. SC589-ezkit or SC584-ezkit or SC573-ezkit), otherwise it may not boot properly.
sc # fatload usb 0:1 0x84000000 sc573-ezkit.dtb reading sc573-ezkit.dtb 10306 bytes read in 30 ms (335 KiB/s) sc # fatload usb 0:1 0x82000000 zImage reading zImage 12452384 bytes read in 7772 ms (1.5 MiB/s)
Verify the read operation:
