Dear All,
I am going to work on RTOS porting (or even we call OSAL porting) from Qualcomm chipset to VIA chipset. Here Qualcomm chipset runs on REX RTOS but we wanted to completely replace to Nucleus RTOS on VIA chipset.
Assumptions: source code is in C, ARM7 processor, JTAG debugger, open ICE as IDE, Hardware is mobile phone
So, to do above...I am really requesting inputs with u all experts for the following concerns...
- What are different types of porting? I think, people will say parameter, API porting and all but I really didn?t understand that...pls explain me with an example.
- What should be the important task while porting for OSAL(Operating system abstraction layer)
- EX: REX OS API takes input as 5 parameter but Nucleus OS takes only 3 or more than 5 parameter, so how to implement this case
Thanks in advance, Plz help me!!!
