Hi all, I am new in using the Nios II sbt tool. When i generate the BSP, in the bsp editor, there is sys_clk_timer and timerstamp_timer option for me to choose. Anyone can explain why we need to specify it or any function on specifying it? What happen if i set both of it to none?

Read the section "Using Timer Devices" starting on page 6-14 (page 145 in the PDF) of the Software Developer Handbook https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/hb/nios2/n2sw_nii5v2.pdf

Hi..thanks. I have read the manual. If I have not assign any timer core in qsys to sys_clk_timer and timestamp_timer, does it mean that the consequences is i cannot use the function like alt_nticks, settimeofday() and etc?
