SPI memory controller
The SPI memory controller debug driver is affected by the common memory commands, but provides commands
spim to perform basic communication with the core. The driver also provides functionality to read the CSD register
from SD Card and a command to reinitialize SD Cards. The debug driver has bindings to the SPI memory device
layer. These commands are accessed via spim flash. Please see Section 3.11.2, “SPI memory device” for more
information. Supported cores: SPIMCTRL
6.14.1. Switches
-edac
Enable EDAC operation (FTMCTRL)
-edac8[4|5]
Overrides the auto-probed EDAC area size for 8-bit RAM. Valid values are 4 if the EDAC uses a quarter
of the memory, or 5 if the EDAC uses a fifth. (FTMCTRL)
-rsedac
Enable Reed-Solomon EDAC operation (FTMCTRL)
-mcfg1
<val>
Set the reset value for memory configuration register 1 (MCTRL, FTMCTRL, SSRCTRL)
-mcfg2
<valn>
Set the reset value for memory configuration register 2 (MCTRL, FTMCTRL)
-mcfg3
<val>
Set the reset value for memory configuration register 3 (MCTRL, FTMCTRL, SSRCTRL)
-pageb
Enable SDRAM page burst (FTMCTRL)
-normw
Disables read-modify-write cycles for sub-word writes to 16- bit 32-bit areas with common write strobe
(no byte write strobe). (MCTRL, FTMCTRL)
ROM switches:
-romwidth
[8|16|32]
Set the rom bit width. Valid values are 8, 16 or 32. (MCTRL, FTMCTRL, SRCTRL, FTSRCTRL)
-romrws
<n>
Set
n
number of wait-states for rom reads. (MCTRL, FTMCTRL, SSRCTRL)
-romwws
<n>
Set
n
number of wait-states for rom writes. (MCTRL, FTMCTRL, SSRCTRL)
-romws
<n>
Set
n
number of wait-states for rom reads and writes. (MCTRL, FTMCTRL, SSRCTRL)
SRAM switches:
-nosram
Disable SRAM and map SDRAM to the whole plug and play bar. (MCTRL, FTMCTRL, SSRCTRL)
-nosram5
Disable SRAM bank 5 detection. (MCTRL, FTMCTRL)
-ram
<kB>
Overrides the auto-probed amount of static ram bank size. Bank size is given in kilobytes. (MCTRL, FTM-
CTRL)
-rambanks
<n>
Overrides the auto-probed number of populated ram banks. (MCTRL, FTMCTRL)
-ramwidth
[8|16|32]
Overrides the auto-probed ram bit width. Valid values are 8, 16 or 32. (MCTRL, FTMCTRL)
-ramrws
<n>
Set
n
number of wait-states for ram reads. (MCTRL, FTMCTRL)
-ramwws
<n>
Set
n
number of wait-states for ram writes. (MCTRL, FTMCTRL)
