Thank you ads-ee for answer. With my EPCS device i can boot both the FPGA configuration and Nios II software. I'm using the Quartus 15.0.When i add the EPCS controller, the DATA, DCLK, ASDI, and nCS signals are not exported to Nios entity. This is why in device and pin options, I configured...
Hi again,
Just to inform you that i have always the same problem.
The behavior doesn't change even if use the alt_write_flash / alt_read_flash functions or alt_epcq_controller_write_block/alt_read_flash functions.
The routine that writes when using alt_write_flash is :
/* write to flash 32...
I want just to precise that in debug mode, I can see that the location
where I write changed but with wrong values.
For example, I'm writing 0x40228f5c to 04FC0000 address, but I can see
this :
04FC0000 2E479120 FFFFFFFF FFFFFFFF FFFFFFFF
I don't find an explication why.
Thanks in advance
Hi all,
I am building a custom system, using an FPGA board with a Nios II processor. I'm using Quartus 15.0 and DE0 NanoBoard( Cyclone IV as FPGA)
My application contains:
1. Clock Source
2. Nios II Processor
3. System ID
4. JTAG UART
5. EPCS Serial Flash Controller
6. PIO
7. SDRAM Controller...
