Hi FPGA experts.I need your help for de1-soc. In the document http://www.mouser.com/catalog/specsheets/de1-soc_user_manual_v06.pdf it is stated that QSPI Flash can contain user data obious thing for he flash memory. Iwant to read/write data to this memory from c code from HPS. I see the pin conection of te FPGA to this memory and can do verilog to access it. But I hope there should be some wise way to solve my task through accessing the memory at some address or so directly from ARM trough this fancy AXI bus.
If you want a very easy-to-use driver, supplied with a working demo (verified to be OK on DE0-nano & DE10-nano), don't hesitate to request our free BSP.www.code-time.com The API of the driver has these 4 basic functions calls: qspi_init(); qpsi_read(); qspi_write(); qspi_erase(); It can't be simpler than that. Regards
Hello i want to do the same.
I am new developer for the Cyclone v SoC.
I want to read and write from the QSPI flash in my HPS baremetal application. I want to write a very simple data in words format.
write data 0xABCD, 0xCDEF, 0x1234
and then read it back.
I checked the following functions but they are not working for me.
I think i need to initialize the qspi and do the other initialization etc before using alt_qspi_write or alt_qspi_read.
Is there any one who developed a c program for QSPI of DE0-NANO-SOC?
is there any built application project doing the simple read and write on QSPI?
