Hi, I write a funcion named IAP and put it in a fixed adress using de "BL51 Locate" table as below: Code: ?PR?Switch_Flash?Iap_asm(0x1000) Now I want to put a constant in a fixed adress. How can I make it together with de directive above? I try to separet both with ";" and "," bu it doesn't work! Example: unsigned char code Tab1 = 0x55; BL51 Locate: Code: ?PR?Switch_Flash?Iap_asm(0x1000) ; ?CO?Tab1(08000h). Anybody can help me please? Thanks
