Part Number: TMS320F28379D
Hello all,
I am doing the SDRAM testing with a f28379D board and have few experiences with SDRAM.
The hardware connection is as attached below. It's a 4M x 16 x 4 banks SDRAM and connects to emif2/cs0.
when I try to get info from TI documentation, I found the information:
1) from f28379D datasheet, it says the EMIF2_CS0 address is from 0x9000 0000 to 0x91FF FFFF and a 3Mx16 size.
2) from TI c2000 ware examples(xxxx_sdram_far_cpu01): the cmd file says:
....
EMIF1_CS0n : origin = 0x80000000, length = 0x10000000
EMIF1_CS2n : origin = 0x00100000, length = 0x00200000
EMIF1_CS3n : origin = 0x00300000, length = 0x00080000
EMIF1_CS4n : origin = 0x00380000, length = 0x00060000
EMIF2_CS0n : origin = 0x90000000, length = 0x10000000
EMIF2_CS2n : origin = 0x00002000, length = 0x00001000
...
Well, the EMIF2_CS0n is same as EMIF1_CS0n, ????
So, here's my question:
1) is the 'EMIF2_CS0n : origin = 0x90000000, length = 0x10000000' reasonable, since the emif2 cs0 only have 3Mx16 address according to datasheet ?
2) with my SDRAM hardware connection, how many rooms in the SDRAM can be actually accessible?
