Hello All.
I use u-boot-1.1.4-davinci u-boot code.
When I looked board/davinci/lowlevel_init.S, I find the code belows.
LDR R0, ACFG3
LDR R1, ACFG3_VAL
LDR R2, [R0]
AND R1, R2, R1
STR R1, [R0]
LDR R0, ACFG4
LDR R1, ACFG4_VAL
LDR R2, [R0]
AND R1, R2, R1
STR R1, [R0]
LDR R0, ACFG5
LDR R1, ACFG5_VAL
LDR R2, [R0]
AND R1, R2, R1
STR R1, [R0]
Here, I have questions about this codes.
Question1
What about ACFG2?
I think I have to add the code ACFG2. Is it right?
Why lowlevel_init.S doesn't have ACFG2 code in this source code?
Question2
If ACFG2 setting doesn't need in the lowlevel_init.S, I think the reset values
would be used after system reset.
But when I looked at the EMIF User's Guide, the reset value of ASIZE field in
AnCR is "0" for 8-bit data bus.
Here is my question, DVEVM board uses 16bit NOR flash memory,
So, Where can I find the A2CR setting values? or Is there any method to set the
A2CR values?
Any comments will help me.
Thanks.
Jaehoon Lee
