Platform designer/NiosII Eclipse: SRAM controller error

Dear all,

Good day, I hope you are doing well. I am trying to add an SRAM controller to my project, but I received the following error in Nios II Eclipse:

INFO: Tcl message: "STDIO character device is jtag_uart_0"
INFO: Tcl message: "System timer device is sys_timer"
SEVERE: CPU "nios2_gen2_0" has no memories connected to its Avalon host(s)
WARNING: Tcl script "bsp-set-defaults.tcl " error: CPU "nios2_gen2_0" has no memories connected to its Avalon host(s)
SEVERE: [Error] altera_hal_linkerx_generator: Required linker section mappings do not exist: "[.entry, .exceptions, .rodata, .rwdata, .text, .bss, .heap, .stack]"
SEVERE: [Error] altera_hal_linkerx_generator: Required linker section mappings do not exist: "[.entry, .exceptions, .rodata, .rwdata, .text, .bss, .heap, .stack]"
SEVERE: nios2-bsp-create-settings failed.
nios2-bsp: nios2-bsp-create-settings.exe failed
nios2-bsp hal . ../../led.sopcinfo  --cpu-name nios2_gen2_0 failed

Please note that I have followed the steps below:

  • IP catalog -> University program -> memory -> SRAM controller.

  • SRAM: sram_avalon_sram_slave is connected to nios_cpu: data_master and instruction_master .

  • nios_cpu -> reset_vector_memory and Exception_vector_memory is to sram.avalon_sram_slave.

  • The base address from SRAM is 0x0000_0000.

  • I have created the top entity module in verilog and all pins are connected.

  • The generated SOPCINFO file for the nios_cpu module has the the above info :

  <assignment>
   <name>embeddedsw.configuration.exceptionSlave</name>
   <value>sram.avalon_sram_slave</value>
  </assignment>
  <assignment>
   <name>embeddedsw.configuration.resetOffset</name>
   <value>0</value>
  </assignment>
  <assignment>
   <name>embeddedsw.configuration.resetSlave</name>
   <value>sram.avalon_sram_slave</value>
  </assignment>

Note:

  • Board Altera DE2-115.

  • Quartus version 22.1.

  • No errors if i try other projects without SRAM.

I would appreciate any advice on this issue.

Thank you.

    How have you set up the BSP, especially the linker script that defines the memories to use for the processor?

    Hi all,

    I'm getting the same error when I'm using onchip_memory_2.0.

    I just installed wsl, but it doesn' work.

    When I open Eclipse this error is shown:
