Hi! Can anyone give me some help. My system: mcu-- 89c669 ;No external RAM and external ROM;keil 710;Rtx_full; I can not define more than 2 tasks.Because system xdata(768byte) is exhaust.How can I use on board edata(1280byte) as stack instead of xdata. I once set ESMM=1 in the start_mx.a51.But I got some link error(L119). Great thanks to you.
The P89C669 has 2k ram (XDATA), where do you get the numbers from? Erik
