max10 remote system update nios with uart

hii i have progressed with the example of doing max10 rsu over uart with nios i have the neek dev board for practicing i have added to the qsys system of the original project that i downloaded fr...

Hello aiedb,

Have you evaluated Demonstrations/uart_usb design in MAX10_NEEK_v.1.0.7_SystemCD.zip?

After confirming the uart_usb design, we recommend to change uart_usb.qpf.

Here is a part of uart_usb.qpf file.

  1. #============================================================
  2. # GPIO
  3. #============================================================
  4. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[0]
  5. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[1]
  6. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[2]
  7. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[3]
  8. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[4]
  9. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[5]
  10. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[6]
  11. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[7]
  13. ….
  15. #============================================================
  16. # UART
  17. #============================================================
  18. set_instance_assignment -name IO_STANDARD "2.5 V" -to UART_RESET_n
  19. set_instance_assignment -name IO_STANDARD "2.5 V" -to UART_RX
  20. set_instance_assignment -name IO_STANDARD "2.5 V" -to UART_TX
  22. ….
  24. set_location_assignment PIN_Y17 -to GPIO[0]
  25. set_location_assignment PIN_AA17 -to GPIO[1]
  26. set_location_assignment PIN_V16 -to GPIO[2]
  27. set_location_assignment PIN_W15 -to GPIO[3]
  28. set_location_assignment PIN_AB16 -to GPIO[4]
  29. set_location_assignment PIN_AA16 -to GPIO[5]
  30. set_location_assignment PIN_Y16 -to GPIO[6]
  31. set_location_assignment PIN_W16 -to GPIO[7]
  33. ….
  35. set_location_assignment PIN_E16 -to UART_RX
  36. set_location_assignment PIN_E15 -to UART_TX

If you want to assign uart pins to GPIO[7:6], here is an example. Red items should be changed.

  1. #============================================================
  2. # GPIO
  3. #============================================================
  4. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[0]
  5. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[1]
  6. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[2]
  7. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[3]
  8. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[4]
  9. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[5]
  10. #set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[6]
  11. #set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to GPIO[7]
  13. ….
  15. #============================================================
  16. # UART
  17. #============================================================
  18. set_instance_assignment -name IO_STANDARD "2.5 V" -to UART_RESET_n
  19. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to UART_RX
  20. set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to UART_TX
  22. ….
  24. set_location_assignment PIN_Y17 -to GPIO[0]
  25. set_location_assignment PIN_AA17 -to GPIO[1]
  26. set_location_assignment PIN_V16 -to GPIO[2]
  27. set_location_assignment PIN_W15 -to GPIO[3]
  28. set_location_assignment PIN_AB16 -to GPIO[4]
  29. set_location_assignment PIN_AA16 -to GPIO[5]
  30. #set_location_assignment PIN_Y16 -to GPIO[6]
  31. #set_location_assignment PIN_W16 -to GPIO[7]
  33. ….
  35. set_location_assignment PIN_Y16 -to UART_RX
  36. set_location_assignment PIN_W16 -to UART_TX

After changing the pin assignment, you need to recompile the design and generate POF again.

hii thanks for reply

my question is not about how to assign the uart pins

i trying to practice the max10 remote update on my neek dev board

and i saw in an741

Remote System Upgrade for MAX 10 FPGA Devices
over UART with the Nios II Processor

there is a file called nios_application.pof as a part of the files needed to do the lab

my question is about how to generate nios_application.pof file that is part of the files that is needed for Programming into external QSPI flash,

this that consists Nios II processor software application hex file only.


i have built the qsys system for the rsu design and also i have the remote_update c source file and my quistion is how do i generate nios_application.pof

    Hello aiedb,

    Sorry for misunderstanding your question.

    You want to run AN741 on MAX10 NEEK instead of Max10 Devkit, right?

    Please me give some time to run the design on Max10 Devkit first.

    Regards,

    Yoshiaki

      hii you are right

      i am trying to run the max10 rsu on neek , i don't have the max10 devkit i have the neek instead

      i found a user guide that explains how to produce the nios_apllication.pof in the appendix i missed it i will try it out hope it will help me , if i have further questions i will get back to you .

      but i noticed if i download the neek remote system update example from altera website , it doesn't come with the qsys sytem file so i can see the system in platform designer , can you send the file maybe ?
