Hi My ST10/C167 target hardware has a BOOT (that starts at 0:0000h) and a separate and independant MAIN application that is downloaded into FLASH memory at 2:0000h. Both applications use serial comm and interrupts, so redirection of the interrupt vectors is necessary in BOOT, before I switch to application. In read the description C166: INTERRUPT VECTOR REDIRECTION but there the JMPS uses fix segment address. I looks that I have to jump into a subroutine that decides where I am (BOOT or application) and than set the interrupt vector (all in assembler, help!). How can I implement the suggested solution mentioned by KEIL above when I use the interrupts in BOOT too? Can anyone help me? I would be very pleased. Regards, Christian
I haven't done that myself. I know that it is easy to relocate the whole interrupt vector table - there is a setting in Target Options/L166 that does that. But that would be a waste of RAM. If you have plenty of RAM, it's not a problem. To get only some of the entries in the interrupt vector table to point to RAM is tricky. I think it can be done using assembler (locating sections to absolute address and placing a JMPS instructions there). You will have to read the manual... Good luck! - Mike
