command line.
nios2-flash-programmer Command-Line Examples
nios2-flash-programmer --cable="Usb-blaster [USB-0]" --base=0x200000\
--program ext_flash.flash
Programs CFI flash memory based at address 0x200000 with input file ext_flash.flash
using a cable named "Usb-blaster [USB-0]"
nios2-flash-programmer --epcs --base=0x02100000 epcs_controller.flash
Programs an EPCS/EPCQ device based at address 0x02100000 with input file
epcs_controller.flash
.
nios2-flash-programmer --base=0x200000 --read=current.srec \
--read-bytes=0,0x10000
Reads 0x10000 bytes from CFI flash memory based at address 0x200000 and writes the
contents to a file named current.srec
nios2-flash-programmer --base=0x200000 --erase=0x8000,0x10000
Erases address range 0x8000 to 0x10000 in CFI flash memory based at address
0x200000
nios2-flash-programmer --base=0x200000 --debug
--base= Required Specifies the base address of the CFI flash memory.
This parameter is the absolute address in the target
design's address space. nios2-flash-programmer
treats addresses in the S-record files as offsets to
the base address.
EPCS Parameters
--epcs Required when
programming an
EPCS/EPCQ serial
configuration device;
defaults off Specifies that the target flash memory is an
EPCS/EPCQ serial configuration device.
--debug Optional; defaults off Prints debug information about the physical memory
inside the EPCS/EPCQ device.
--base= Required Specifies the base address of the EPCS/EPCQ device.
Notes to Table 3–2 :
(1) The --cable parameter is only needed if there are multiple download cables connected to the host computer. To determine the cable names,
run jtagconfig.
(2) The --device parameter is only needed if there are two or more processors in different devices with the same instance ID. To determine the
JTAG device index, run jtagconfig.
(3) There are two ways to find the correct value of the instance ID for a processor. The easiest is to use the Nios II Flash Programmer GUI to create
a sample flash programmer script. Refer to Chapter 2, Using the Flash Programmer GUI for details. Alternatively, open
name>.jdi, in the Quartus II project directory. Locate the Nios II processor node by finding a value of hpath containing name>=. The instance ID is specified as instance_id.
(4) In system.h and in your board support package (BSP), the system ID base address is specified by SYSID_BASE.
(5) In system.h and in your BSP the system ID value is specified by SYSID_ID.
(6) In system.h and in your BSP, the system ID time stamp is specified by SYSID_TIMESTAMP.
