OK6410 Development Board System installation---embedded regression second article

1. The embedded system needs to be installed on the nandflash of the Development Board or on the SD card

2. Embedded Linux systems that need to be installed can be divided into three parts

1> Bootloader Boot OS

3> application, user files, configuration files

3. What are the steps to install embedded Linux systems into Nandflash?

Here first use the Left DD command/windows burn write software mode

1. Insert the standard SD card into the notebook via the card slot

2. Quick Format SD Card

3. Burn-Write start-up installer

I also have this problem when I write today. The desktop of the school has been used very smoothly! Baidu has this method and then it's OK.

Sd_writer this software, but each write will be wrong, is the wrong operation method. The correct way to do this is as follows:

1. First run the Sd_writer software with administrator privileges

2.? A drive letter will appear after scan, e.g. J

3. Must be required first format,windows will pop up a dialog box to run for a while

4. Select the bin file to burn, it's OK to appear

4. After the burn is finished, launch the installation launcher on the Development Board

1> the SD card into the Development Board slot, the board is set to SD card boot, that is, the dial switch is 0001 1111

2> Press the space bar of the keyboard before power on, then power on, connect the terminal via SECURECRT (first connected),

5. Use the above download to install the bootloader and USB download cable, from the PC to install embedded Linux system download to the Development Board

The following installs Uboot and Linux in turn

First step: Format the NAND flash

Step Two: Select Item "3": Burn image from USB download bootloader

Choose 1 Flash u-boot here

Then install the DNW USB drive on the virtual machine and download the target file via DNW to the Development Board

This is to upload the image file to the memory of the Development Board. 5000000 for the Board memory first address and the boot loader will automatically copy the in-memory image to the Nandflash.

So uboot download it now and then download the Linux kernel

Serial Terminal Select the second item: Flash Kernel

Can see download success:

Then download the file system: Here the serial terminal selects the third item

Then download the appropriate file system with DNW under the Linux virtual machine

This download process is probably longer, compared to the 123M file system is still quite large

See here 100%complete that file system download complete!

Then turn off the board power and switch the development board to nandflash boot! It's OK! The entire Linux system is installed on the Development Board!

Turn on the power of the board again, here is a picture of the successful installation:

According to the country embedded in the video to go, think six months ago these operations have been quite skilled, six months after a lot of steps impression or forget, but the general process still remember, today reinstall the way to write notes recall familiar!
