Booting a bare metal application from QSPI flash

Hi, I'm developing a bare metal application on the Arrow SOCkit demo board. I want the HPS to boot the application from QSPI flash. Everything works fine when I'm using the debugger, but when i...

Hello,

I have a custom board with cyclone V SOC . I have a 1Gbit QSPI flash attached to the HPS portion of SOC. I want to boot the HPS with qspi flash. I able to do it debug mode. But not able to do it in program mode. what i mean is that i am able to load the rbf files into the qspi flash and read back this files and program the fpga successfully in debug mode. But when i try to do it program mode it is not working. I have generated preloader_-mkpimage.bin file with all the necesssary settings as mentioned in HPS qspi boot guide documentation. i load this preloader-mkpimage in 0x00000000 address of QSPI flash using the commands in SOC Command shell. then i load my application bin file generated after compilation of my design at 0x60000 address of flash by using commands in SOC EDS Command shell. Both this operation is successfull. MSEL pins are correctly selected for QSPI Boot. When i reboot the equipment the system is not booting. Am i missing certain settings at bsp generation or in make file or the linker file. Please specify.

Regards

Avi

We made our own baremetal tutorial.
this tutorial explains the start to end complete procedure for making the baremetal application on the HPS.

overview about this tutorial

  1. you need to make the DDR3 settings in the QSYS HPS.
  2. you need to use the “hps_isw_handoff” generated by QSYS HPS and make the preloader from bsp editor.
  3. do the settings of the bsp editor so that you can boot from QSPI.
  4. make the preloader and store the preloader on the QSPI.
  5. make the binary image of your baremetal application using the fromelf command in DS-5 Build steps.
  6. add the baremetal header to your binary file which is generated from your c code compilation.
  7. program this binary file on the QSPI and power off and on your device.

now you are successful to boot your c program
