Hello guys!!
i need some help with my new niosII core. i tried to program a Ep2C20 with a niosII softcore. but it doesn't work till now.
my system configurations are:
- nios II core (nios II/e, reset vector: onchip_mem offset: 0x00,
exception vector : onchip_mem offset: 0x20,
no caches or memory interfaces,
no advanced features,
jtag debug module level 1,
no custom instructions
)
- out_pio (7-bit output port only)
- onchip_mem (ram-writable,
block type auto,
initialize memory content is checked,
data width : 32-bit, memory size : 4096 bytes
read latency : slave s1
)
if i try to prgram compiled core with the led demo of the nios ide nothing happens. but if i try to program my nios II development kit Ep2C35 everythimng looks fine.
what's the reason for this?? can anybody help me please?? what are the minimum requirement of a niosII core with onchip_mem core?? what's the ideal size of the onchip_mem??
thank you very much for help!!!
