Hello Sid, How well is your asm? You have some digging to do.
The reason for incompatibility is that there is no common calling convention. First you'll have to find out what the options were they used for building the blestack library. Then you'll have to find out what that means in terms of passing parameters and receiving return values. If there is anything located in memory instead of on stack, you'll have to reserve that space from SDCC. Then you must create wrapper functions around the library functions that make the conversion without disturbing the stack. You can also try to find out who owns the blestack library. If it's TI's then they might be persuaded to also release it as an SDCC library. It's in their interest to sell IC's. But if it's IAR's who only gave this to TI to promote their own tools, then it's unlikely you can get it for SDCC.
