A simple method to enable U-boot to start Linux

1. the following commands have been used for kernel porting and file system debugging for a long time:

# TFTP 0x30008000 zimage

# Go 0x30008000

Normal start,

Note: The above zimage call has been written into the nand flash file system.

 

2. In fact, the above command can be used as a special environment variable for U-boot to automatically start "U-boot + Linux + File System ".

(1) first write zimage into NAND Flash

# TFTP 0x30008000 zimage

# NAND erase 0x40000 0x3c0000

# NAND write. jffs2 0x40000 0x200000 (My zimage is about 2 m)

(2) set the U-boot environment variable

## Saveenv

 

As for how to use U-boot to transmit startup parameters, we will try again later when we find this method convenient.
