The below steps are used to update composite firmware image in FlexSPI NOR flash and SD/eMMC card using an SD card.
- Load composite firmware image on SD card
- Option 1: Using HxD editor on Windows system
- Option 2: Using Linux system
- Program updated composite firmware in SD card
- Program updated composite firmware in FlexSPI NOR flash (DEV#0 and DEV#1)
- Program updated composite firmware in eMMC card
NOTE: Examples shown below use the LX2160ARDB Rev 2 image names. The same examples are applicable for LX2160ARDB Rev 1 also by replacing the Rev 2 image name with the corresponding Rev 1 image name.
Step 1: Load composite firmware image in SD card
Option 1: Using HxD editor on Windows system
The below steps describe how to use an HxD editor on a Windows machine to program firmware image on SD card without partitioning the card.
NOTE: Use the following link to download the HxD editor for Windows: https://mh-nexus.de/en/hxd/.
- Download composite firmware image on Windows machine using the following links:
- For LX2160ARDB Rev1:
- For LX2160ARDB Rev 2:
- Format SD card.
- Open HxD editor and run as administrator.
- Open firmware_lx2160ardb_rev2_uboot_sdboot.img binary file in HxD editor.
- Copy the binary file (CTRL + A and CTRL + C).
- Plug the SD card either directly into the slot available on your Windows machine or using a memory card adapter/reader.
- Open disk (SHIFT + CTRL +D).
Open disk NOTE: Uncheck the 'Open as Readonly' option while opening the disk.
- Go to SD block (or sector) 8 (0x1000).
HxD Editor - Sector 8
- Paste the copied binary image content (CTRL + B). Make sure to copy the image at SD block no. 8.
- Save the content.
- Repeat above steps to load firmware_lx2160ardb_rev2_uboot_xspiboot.img and firmware_lx2160ardb_rev2_uboot_emmcboot.img binary image in SD card.
For example: Load firmware_lx2160ardb_rev2_uboot_xspiboot.img image in SD card at block no. 150500 and firmware_lx2160ardb_rev2_uboot_emmcboot.img image in SD card at block no. 300500.
NOTE: Make sure that you load these images in SD blocks so that the images do not get overwrite.
- Eject the SD card.
Option 2: Using Linux system
- Download composite firmware image on Linux machine using the following links:
- For LX2160ARDB Rev1:
- For SD boot: $ wget https://www.nxp.com/lgfiles/sdk/lsdk2004/firmware_lx2160ardb_uboot_sdboot.img
- For FlexSPI boot: $ wget https://www.nxp.com/lgfiles/sdk/lsdk2004/firmware_lx2160ardb_uboot_xspiboot.img
- For eMMC boot: $ wget https://www.nxp.com/lgfiles/sdk/lsdk2004/firmware_lx2160ardb_uboot_emmcboot.img
- For LX2160ARDB Rev 2:
- For SD boot: $ wget https://www.nxp.com/lgfiles/sdk/lsdk2004/firmware_lx2160ardb_rev2_uboot_sdboot.img
- For FlexSPI boot: $ wget https://www.nxp.com/lgfiles/sdk/lsdk2004/firmware_lx2160ardb_rev2_uboot_xspiboot.img
- For eMMC boot: $ wget https://www.nxp.com/lgfiles/sdk/lsdk2004/firmware_lx2160ardb_rev2_uboot_emmcboot.img
- For LX2160ARDB Rev1:
- Format SD card (optional, required if the card already has some data so to ensure that images have been loaded to card without conflicting with the existing data).
- Load composite firmware image to SD card.
- For SD boot: dd if=firmware_lx2160ardb_rev2_uboot_sdboot.img of=/dev/sdb bs=512 seek=8
- For FlexSPI boot: dd if=firmware_lx2160ardb_rev2_uboot_xspiboot.img of=/dev/sdb bs=512 seek=150500
- For eMMC boot: dd if=firmware_lx2160ardb_rev2_uboot_emmcboot.img of=/dev/sdb bs=512 seek=300500
- Eject the SD card.
Step 2: Program updated composite firmware in SD card
NOTE: Since the updated composite firmware is now available at required block (SD start block no.
- Insert the SD card in SD slot of LX2160ARDB.
- Set switch settings to boot from SD card : SW1[1:4] = 1000
- Restart the board.
The board boots from updated composite firmware (SD boot) image loaded in the SD card. The U-Boot log displays:
Model: NXP Layerscape LX2160ARDB Board
Board: LX2160ACE Rev2.0-RDB, Board version: B, boot from SD
Step 3: Program updated composite firmware in FlexSPI NOR flash (DEV#0 and DEV#1)
- Insert the SD card in SD slot of LX2160ARDB.
- Set switch settings to boot from SD card=> SW1[1:4] = 1000
- Restart the board and stop at U-Boot prompt.
- Load firmware_lx2160ardb_rev2_uboot_xspiboot.img at 0xa0000000 (DDR address) using the following command:
=> mmc read 0xa0000000 <start_block_number> <block_count>
where, <start_block_number> - start block number in SD card where you have loaded the firmware. For example, if you have loaded firmware at SD card block 150500, start_block_number in hex is 24be4
<block_count> - number of blocks in SD card that needs to be read as per the file size. It is calculated as ‘file size /512’ + ‘few sectors for rounding up so that last block is not missed’. If firmware file size is 52158124 (31bdeac hex), block_count is 52158124/512 = 101871 (18DEF hex) + 10 (A hex) = 101881 (18DF9 hex).
For example: => mmc read 0xa0000000 24be4 18DF9
- Program default FlexSPI NOR flash:
=>sf probe 0:0
=>sf update 0xa0000000 0x0 <firmware_lx2160ardb_rev2_uboot_xspiboot.img _filesize_in_hex>
For example: => sf update 0xa0000000 0x0 31BDEAC
- Program alternate FlexSPI NOR flash:
=> sf probe 0:1
=> sf update 0xa0000000 0x0 <firmware_lx2160ardb_rev2_uboot_xspiboot.img _filesize_in_hex>
- Restart the board to boot from FlexSPI NOR flash 0 (DEV#0).
- Switch settings to boot from DEV#0: SW1[1:8] = 1111 1000
-
The U-Boot log shows the following message:
Model: NXP Layerscape LX2160ARDB Board
Board: LX2160ACE Rev2.0-RDB, Board version: B, boot from FlexSPI DEV#0
- Restart the board to boot from FlexSPI NOR flash 1 (DEV#1) as well.
- Switch settings to boot from DEV#1
- SW1[1:4] = 1111 1001
- Switch settings to boot from DEV#1
The U-Boot log shows the following message:
Model: NXP Layerscape LX2160ARDB Board
Board: LX2160ACE Rev2.0-RDB, Board version: B, boot from FlexSPI DEV#1
Step 4: Program updated composite firmware in eMMC card
- Insert the SD card in SD slot of LX2160ARDB.
- Set switch settings to boot from SD card: SW1[1:4] = 1000
- Restart the board and stop at U-Boot prompt.
- Load firmware_lx2160ardb_rev2_uboot_emmcboot.img at 0xa0000000 (DDR address) using the following command:
=> mmc dev 0; mmc read 0xa0000000 <start_block_number> <block_count>
where, <start_block_number> - start block number in SD card where you have loaded the firmware. For example, if you have loaded firmware at SD card block 300500, start_block_number in hex is 495D4
<block_count> - number of blocks in SD card that needs to be read as per the file size. It is calculated as ‘file size /512’ + ‘few sectors for rounding up so that last block is not missed’. If firmware file size is 52158124 (31bdeac hex), block_count is 52158124/512 = 101871 (18DEF hex) + 10 (A hex) = 101881 (18DF9 hex).
For example: => mmc read 0xa000000 495D4 18DF9
- Program eMMC card.
=> mmc dev 1; mmc write 0xa0000000 8 18DF9
- Restart the board to boot from eMMC.
Set switch settings to boot from eMMC card.
SW1[1:8] = 1001 1000
The U-Boot log shows the following message:
Model: NXP Layerscape LX2160ARDB Board
Board: LX2160ACE Rev2.0-RDB, Board version: B, boot from eMMC
