so what’s my problem????

Frequent ContributorHi KPhan4,
I suspect your JTAG frequency might be the root cause for .elf file not work.
Can you kindly try to reduce your TCK frequency to 6 MHz (default value)?
Below link is the command to change TCK frequency (on page 14= 2.8. Changing the TCK Frequency)

Kindly try it out with your design and let me know the result.
Thanks

Error: no param JtagClock
I programed .sof to flash and run Debug app on Eclipse. It worked. So Nios’ reset vector and reset value when i convert .elf cause for it not work???
Frequent ContributorKPhan4,
For latest design development, we recommend to use sof file rather than .elf file.
Thanks
