Change value of ?B_NBANKS

It works fine for me. What version of the tools are you using? Did you make any other changes in the L51_BANK.A51 file?

Jon

I have made some changed on L51_bank file. I used ?B_MODE equ 4, so i need to add some code for switch the bank.
I have try to minimize the switch bank code that i added. how to solve this problem?
my C51 compiler is 6.02, A51 - 6.02, BL51 - 4.02 and OH51 - 2.5

Thanks

Early versions of the L51_BANK file did not support custom bank-switch code that was larger than 256 bytes.

Later versions DO support that. The latest version of the tools provides the following information in the L51_BANK file:

; 2. If the bank switch macros and the additional control code generate more  *
;    than 256 bytes, you need to set the LONG_MACRO flag below.  The error    *
;    message "BANK SWITCH CODE BIGGER THAN 256 BYTES, SET LONG_MACRO TO 1"    *
;    is generated in case that this is required.                              *
;                                                                             *
LONG_MACRO      EQU  0    ; 0 default, for normal macros and up to 8 banks    *
;                         ; 1 big macro code or many banks                    *

What version i should download

I'm not sure exactly when the LONG macro was added. I'd download the latest V7 update and use it.
