BUBT (Burn ATF) command |
||||
-------------------------- |
||||
Bubt command is used to burn a new ATF image to flash device. |
||||
|
||||
The bubt command gets the following parameters: ATF file name, destination device and source device. |
||||
bubt [file-name] [destination [source]] |
||||
- file-name Image file name to burn. default = flash-image.bin |
||||
- destination Flash to burn to [spi, nand, mmc]. default = active flash |
||||
- source Source to load image from [tftp, usb]. default = tftp |
||||
|
||||
Examples: |
||||
bubt - Burn flash-image.bin from tftp to active flash |
||||
bubt latest-spi.bin nand - Burn latest-spi.bin from tftp to NAND flash |
||||
|
||||
Notes: |
||||
- For the TFTP interface set serverip and ipaddr. |
||||
- To burn image to SD/eMMC device, the target is defined |
||||
by parameters CONFIG_SYS_MMC_ENV_DEV and CONFIG_SYS_MMC_ENV_PART. |
||||
|
||||
Bubt command details (burn image step by-step) |
||||
---------------------------------------------- |
||||
This section describes bubt command flow: |
||||
|
||||
1. Fetch the requested ATF image from an available interface (USB/SD/SATA/XDB, etc.) |
||||
into the DRAM, and place it at <load_address> |
||||
Example: when using the FAT file system on USB flash device: |
||||
# usb reset |
||||
# fatls usb 0 (see files in device) |
||||
# fatload usb 0 <load_address> <file_name> |
||||
|
||||
2. Erase the target device: |
||||
- NAND: # nand erase 0 100000 |
||||
- SPI: # sf probe 0 |
||||
# sf erase 0 100000 |
||||
- SD/eMMC: # mmc dev <dev_id> <boot_partition> |
||||
|
||||
Notes: |
||||
- The eMMC has 2 boot partitions (BOOT0 and BOOT1) and a user data partition (DATA). |
||||
The boot partitions are numbered as partition 1 and 2 in MMC driver. |
||||
Number 0 is used for user data partition and should not be utilized for storing |
||||
boot images and U-Boot environment in RAW mode since it will break file system |
||||
structures usually located here. |
||||
The default boot partition is BOOT0. It is selected by the following parameter: |
||||
CONFIG_SYS_MMC_ENV_PART=1 |
||||
Valid values for this parameter are 1 for BOOT0 and 2 for BOOT1. |
||||
Please never use partition number 0 here! |
||||

CONFIG_SYS_MMC_ENV_PART=1 |
||||
Valid values for this parameter are 1 for BOOT0 and 2 for BOOT1. |
||||
Please never use partition number 0 here! |
||||
- The partition number is ignored if the target device is SD card. |
||||
- The boot image offset starts at block 0 for eMMC and block 1 for SD devices. |
||||
The block 0 on SD devices is left for MBR storage. |
||||
|
||||
3. Write the ATF image: |
||||
- NAND: # nand write <load_address> 0 <ATF Size> |
||||
- SPI: # sf write <load_address> 0 <ATF Size> |
||||
- SD/eMMC: # mmc write <load_address> [0|1] <ATF Size>/<block_size> |
||||
