The goal of the document is to illustrate how to build SP7021 Linux image for booting from SPI-NAND flash on SP7021 boards, and how to write SP7021 images to the SPI-NAND flash.

First, you need to get source files from git server of SP7021. Second, you need to run make to build all images of SP7021. After make processes complete successfully, it will create a binary file named ISPBOOOT.BIN. This binary file is packed with all necessary codes and images to write to the SPI-NAND flash. Third, you need to copy the built ISPBOOOT.BIN file to root directory of an USB flash drive. Finally, plug the USB flash drive into an USB socket of SP7021 board, set DIP-SW to “boot from USB”, and turn on power of the SP7021 board. After power-on, SP7021 will load and run ISPBOOOT.BIN. The codes, in ISPBOOOT.BIN, will then take control and write all images to SPI-NAND flash. After completing writing images to SPI-NAND, please set DIP-SW to “boot from SPI-NAND”.

Now you are ready to turn off and on SP7021 power again to boot Linux from SPI-NAND flash. For details, please follow the following steps.

1. Download source files

Source files of SP7021 can be downloaded from GitHub or Yocto server of SP7021. Refer to https://github.com/sunplus-plus1/SP7021 or 2. HOW TO GET SOURCE FILE AND PACKAGE. Refer to report of ll command for the contents of top folder of source of SP7021:

wellslu@scdiu3:~/q628/nand$ ll total 52 drwxr-xr-x 12 wellslu sp 4096 Oct 15 12:03 ./ drwxr-xr-x 19 wellslu sp 4096 Oct 15 12:03 ../ drwxr-xr-x 8 wellslu sp 4096 Jul 8 18:22 boot/ drwxr-xr-x 4 wellslu sp 4096 Aug 24 09:28 build/ drwxr-xr-x 7 wellslu sp 4096 Jul 28 09:33 crossgcc/ drwxr-xr-x 6 wellslu sp 4096 Jul 8 18:22 eCos/ drwxr-xr-x 9 wellslu sp 4096 Jul 8 18:22 freertos/ drwxr-xr-x 8 wellslu sp 4096 Aug 17 15:17 ipack/ drwxr-xr-x 7 wellslu sp 4096 Jul 8 18:22 linux/ -r--r--r-- 1 wellslu sp 23 Jul 8 18:22 Makefile drwxr-xr-x 4 wellslu sp 4096 Jul 8 18:22 nonos/ drwxr-xr-x 7 wellslu sp 4096 Jul 8 18:22 .repo/ drwxr-xr-x 3 wellslu sp 4096 Jul 8 18:22 yocto/

2. Configure environment

Run make config command on top folder. After configuration menu pops up, first, choose board you want to build image for. For example, press 1 to choose “SP7021 Ev Board”. Second, press 1 to choose to use C chip (CA7 x4). Finally, press 2 to choose to boot from SPI-NAND flash and then enter to start to configure building environment. Refer to screenshot below,

make config starts to build compiler environment. It may take a few minutes. Please wait for make config completing the processes.

3. Build all images and ISP files

Run make all command to start to create all images of SP7021. It may take several minutes to complete. After make all completes, you will see screen like:

From information on screen, 7 partitions are created (in the binary file ISPBOOOT.BIN). For example, size of uboot2 partition is 0x90400 (590,848 bytes). The maximum allowable size of uboot2 is 0x100000 (1,048,576 bytes). 56.35% of maximum size is used. Size of dtb partition is 0x5000 (20,480 bytes). 7.81% of maximum size is used. Size of kernel partition is 0x3e9800 (4,102,144 bytes). Size of rootfs partition is 0x744000 (7,618,560 bytes).

4. List of built images

All built image files are stored at folder out. Refer to screenshot of output of ll out command:

xboot.img is an image file of x-boot. x-boot is the first stage boot-loader. It is the first code SP7021 loads and runs when SP7021 is powered on. When it takes control, it loads and runs u-boot. u-boot.img is an image file of u-boot. u-boot is the second stage boot-loader. When it takes control, It loads and runs Linux kernel image. uImage is an image file of compressed Linux kernel with u-boot header. rootfs.img is an image file of root file-system of Linux. dtb is device-tree blob file. a926.img is an image file for processor A926. Processor A926 is designed for taking care of real-time tasks. x-boot, u-boot, and all other images are packed into binary file ISPBOOOT.BIN.

5. Copy ISPBOOOT.BIN to an USB flash drive

Copy the built ISPBOOOT.BIN file to root directory of an USB flash drive. Note that the USB flash drive should be formatted to DOS/Windows FAT32 file-system. SP7021 can only load files from an USB flash drive which is formatted to FAT32 file-system. Note that FAT32 file-system should be in the first or the sole partition of the USB flash drive.

6. Set DIP-SW to “boot from USB”

Set DIP-SW (boot-select switch) to “boot from USB”. For example, if you are using SP7021 Ev Board, please set DIP-SW to OFF-OFF-OFF-OFF-ON-OFF (1-1-1-1-0-1) for booting from USB flash drive. Refer to picture below, DIP-SW is set to OFF-OFF-OFF-OFF-ON-OFF.

Refer to https://sunplus.atlassian.net/wiki/spaces/doc/pages/460981046 for details of boot selection of SP7021.

7. Write all SP7021 images to SPI-NAND flash

Plug your USB flash drive which contains ISPBOOOT.BIN into either USB socket of SP7021 board. Install UART console and set terminal to 115,200 bps. Finally, turn on power of SP7021 board. After power on, SP7021 starts to ”boot from USB” drive. It first loads x-boot from ISPBOOOT.BIN in USB flash drive. x-boot loads u-boot. u-boot will then loads all images, verify md5-checksum and write them to SPI-NAND one by one. Wait for writing to complete. Finally, you will see screen like:

“ISP all: Done” means all images were written to SPI-NAND successfully.

Note that in-system-program (ISP) of SP7021 does not support USB hub. The USB flash drive for ISP should be plugged into USB socket of SP7021 board directly.

If you are using Banana Pi BPI-F2P boards, please plug you USB flash drive to the micro USB socket for ISP. It is the only USB socket that is connected to SP7021 directly.

8. Boot Linux from SPI-NAND flash

Set DIP-SW (boot select switch) to “boot from SPI-NAND flash”. For example, if you are using SP7021 Ev Board, please set DIP-SW to OFF-OFF-ON-ON-OFF-ON (1-1-0-0-1-0) for booting from SPI-NAND flash. Refer to picture below:

DIP-SW is set to OFF-OFF-ON-ON-OFF-ON. Now, you are ready to boot SP7021 Linux from SPI-NAND flash. Turn on power of SP7021 board again to boot system.

9. In-system program (ISP) from an SD card

Note that you can also copy your ISPBOOOT.BIN file to root directory of a micro SD card to do in-system-program to eMMC device. The SD card be formatted to DOS/Windows FAT32 file-system. Note that SP7021 only detects ISPBOOOT.BIN in the first partition.

Set DIP-SW (boot-select switch) to “boot from SD card”. For example, if you are using SP7021 Ev Board, please set DIP-SW to OFF-OFF-OFF-OFF-ON-ON (1-1-1-1-0-0) for booting from SD card.

Plug your SD card into micro SD socket of SP7021 board, install UART console, and then turn on power of SP7021 board. SP7021 will start to do ISP from SD card.

Appendix A. Layout of partitions of SPI-NAND flash

Refer to layout of partitions of a 256MiB SPI-NAND flash. There are a GPT (GUID Partition Table) and 9 partitions in SPI-NAND flash. The figures in parenthesis of each partition is the maximum size of the partition. Size of partition rootfs extends to end of SPI-NAND flash.
