Hello,
I am using code banking for my 106 KB code, divided into 2 code banks. The linker is BL51. The output listing(m51 file) generated by keil is as follows:
BL51 BANKED LINKER/LOCATER V6.11, INVOKED BY: C:\KEIL\C51\BIN\BL51.EXE COMMON {.\output\L51_BANK.obj}, COMMON {.\output\mic40.obj}, BANK0 {.\output\Line40.obj}, BANK1 >> {.\output\print40.obj} TO .\output\832V2 BANKAREA (0X3710, 0XFFFF) REGFILE (.\output\832V2.ORC) PRINT (.\listing\832 >> V2.m51) RAMSIZE (256) BANK0 (?CO?LINE40 (0X8000), ?PR?MAIN?LINE40 (0XFF00)) BANK1 (?CO?PRINT40 (0X8000)) OVERLAY (LIN >> EINIT ~ RUNLINEMANAGER, CREATETASK !

In the above text, the notations are as follows : a) Common(Mic40.c),Bank0(Line40.c), bank1(print40.c). b) ONTIMERISR is Timer 0 interrupt routine. c) ONSERIALPORTISR is Serial interrupt routine, and d) main() is located at 0xFF00 in bank 0 ****************************************************************************** Now, I compiled my code using LX51 linker of Keil. The code compilation is ok. The output listing(map file) generated is also similar to the one in m51 format. It is as shown:
LX51 LINKER/LOCATER V4.25, INVOKED BY: C:\KEIL\C51\BIN\LX51.EXE COMMON {.\output\L51_BANK.obj}, COMMON {.\output\mic40.obj}, BANK0 {.\output\Line40.obj}, BANK1 >> {.\output\print40.obj} TO .\output\832V2NX BANKAREA (0X003710, 0X00FFFF) REGFILE (.\output\832V2NX.ORC) PRINT (.\lis >> ting\832V2NX.map) OVERLAY (LINEINIT ~ RUNLINEMANAGER, CREATETASK !

The problem is that my system is not booting. I suspect that the control is not detecting main(), and is not executing the primary initializations in main().
Will LX51 support code banking? What parameters have to be modified in the Keil Target options?
Please advise.
Hi,
There is any difference in generating the code with LX51 linker; If code banked project working perfectly with BL51 Linker; and not working on LX51 linker on the target hardware;
What other parameters we have to check?
our other project without code banking compiled in LX51, and working OK on real time hardware.
please advise.
LX51 supports code banking. So if there is a problem, it might be related to the way you program the HEX file into the memory.
Maybe this helps: http://www.keil.com/support/docs/2349.htm
