Hello,
Since my previous thread closed, my news are:
[1] Our ASRAM 1Mx16bit doesn't work as expected, therefore we would like to reconfirm the address map and wirings.
[2] A new project happens. This time it will have 512KBx8bit ASRAM on the EMIF. Therefore please tell me about that also.
I'm sorry for long questions.
They repeat the same questions for a couple of ASRAM types, 1Mx16bit and 512Kx8bit:
From the F28075 DS, p155: Table 6-3. EMIF Chip Select Memory Map
Q1: Please assume EMIF1_CS2n to control ASRAM 1Mx16bit:
Q1-1: I think that the Addr for CPU (0x0020 0000) to (0x002F FFFF) should not be accessed. Do you agree ?
Q1-2: Please tell me if any concerns in the table.
Q1-3: I think "x=18" for ASRAM 1Mx16bit. Do you agree ?
Q2: Please assume EMIF1_CS2n to control ASRAM 512Kx8bit:
Q2-1: I think that the Addr for CPU (0x0018 0000) to (0x002F FFFF) should not be accessed. Do you agree ?
Q2-2: Please tell me if any concerns in the table.
Q2-3: I think "x=16" for ASRAM 512Kx8bit. Do you agree ?
