JLINK+ADS+mini2440 configuration ///Configure J-Link to burn bootloader for mini2440

When using ADS1.2 and entering the AXD debugging environment, the message "the session file could not be loaded" appears

solution:

1: Place the project file in a directory that does not contain Chinese paths.

2: In AXD->confing Interface, remove the option in front of save and load default session in general.

1: Load the initialization file in the session file in AXD->options->configure interface. The specific content is as follows:

Setmem 0x53000000 0x00000000 32 

Setmem 0x4A000008 0xFFFFFFFF 32 

Setmem 0x4A00001C 0x000007FF 32

2. In AXD --> options --> configure processor, remove the option for semihosting and click clear all.

3. When using ADS for the first time, you need to configure J-LINK in AXD. Select JLinkRDI.dll in the installation directory of J-LING in AXD>OPTION>CONFIGURE TARGET, then click CONFIGURE configuration, and select the chip reset time as 2000ms to debug normally.

Configure J-Link to burn bootloader to mini2440                                   

Using J-Link can actually burn without configuration, but the speed is very slow

Why? Because it is not running in the board's memory.

Beginners may not know how to configure J-Flash, so you can refer to my configuration file (use with caution, burning BIOS may easily cause problems).

【DownUrl】 J-Link burns mini2440 BIOS configuration file

-----------------------------------------------------------------------------------------------------------------

If you configure it yourself, the basic configuration is as follows. You should refer to the init script included in the CD and fill in the initialization options yourself.

The main configuration process is as follows:

Menu: [Options]-->[option settings]

1. Gneral: Connectioin to J-link --> USB: Device 0

2. Target Interface: Keep the default settings.

3. CPU:

Core --> Auto, Little endian

Use target RAM (faster) --> Addr: 40000000 64KB (mainly this, it will be too slow if not used)

Fill in the initialization sequence as shown below. It is also copied from the H-Jtag script. I have simply commented on it.
