I am porting u-boot-1.1.4 for one of our board. I have the below code in my header file.

#if (CONFIG_COMMANDS & CFG_CMD_KGDB) #define CFG_CBSIZE 1024 /* Console I/O Buffer Size */ #else #define CFG_CBSIZE 256 /* Console I/O Buffer Size */ #endif

I am getting a compile error: Invalid token in expression

Am I missing something? Thanks in advance

There is probably more code (or, to be precise, more definitions) in this file...

...

#if (CONFIG_COMMANDS & CFG_CMD_KGDB) #define CFG_CBSIZE 1024 /* Console I/O Buffer Size

*/

...

#else #define CFG_CBSIZE 256 /* Console I/O Buffer Size

*/

...

#endif

I am getting a compile error: Invalid token in expression

And there was no line number or so with this error message?

...

Am I missing something?

Yes: providing enough of context for a helpful reply.

Best regards,

In looking over the DULG web site I could not find a place where I could download a pdf version of the manual for reading off line. Where would I find something I can download and read when not connected to the internet?
