The 2416 processor is so cool and the manual is so cool.

After getting the 2416 host, we started the routine process. We started to look at the 2416 Bootloader and manual, familiarize ourselves with the overall architecture, read the memory ing table, and found that the memory start address is

0x30000000, but the Manual cannot be found. It's strange.

The manual is hard to find. It was so depressing to write 0x3000_0000 in the manual.

The 2416 manual is simpler than 2440 and harder to understand than 6410.

 

Now let's take a look at some small things.

 

This is connected to nscs0. My current memory is unstable, and the amount of memory has something to do with the drive capability. Let's take a look at it first.

3.18 dscn (drive strength Control)

Dsc_nscs0 [11: 10] nscs0 drive strength.
00 = 4. 9mA 01 = 9. 8mA
10 = 14. 8mA 11 = 19. 7mA

The default value is 10 = 8mA. Check whether the configuration is correct. If not, try it tomorrow.
