Honored ContributorCan someone Help with the steps involved in modifying an existing bsp/HAL driver for Nios.
I need to add few Features in the exiting driver. I cannot even add print statements as the "generate BSP" would overwrite all of my changes. Please provide me with detailed steps.
Honored ContributorYou shouldn't be changing the auto generated HAL drivers. If you want to add your own custom files start a new .h and .c files in your project folder and# include the generated HAL files (or not if you don't want to use the auto generated drivers).
If you don't include a driver in your main program then it won't be used. You can make your own drivers (by including system.h) as described above.Honored ContributorHi, I've managed to do this. I've written a very basic Avalon-Memory-Mapped component with a few registers which I wanted to incorporate into a .qsys file and be seen by a Nios. Attached in the zip file is the component "avalonmm_regspace_vhdl.hdl" and the .tcl files required to incorporate it into the hardware " avalonmm_regspace_vhdl_hw.tcl" and then the software (ie. driver) "avalonmm_regspace_vhdl_sw.tcl". In Eclipse as long as when you generate your BSP it looks into the directory containing the ..._sw.tcl file it should incorporate the driver into a "driver" directory.
Hope this helps. CindyHonored ContributorThanks Cindy,
I will check this out and provide you with the updates Regards Chandramohan
