I'm using ELKS kernel in a embedded system with an AT architetture, Elan SC400 processor, 2mb RAM, - 640KB real, 1MB extended 2mb flash eprom as HD Floppy 1.44 which now I'm using to boot kernel Image A20 gate for Extended Memory XT keyb on elan controller two serial port For use 1.0.1 kernel in this system I added code for implement keyboard in SC400 Microcontroller (change an address for the data-register keyb from original code); Kernel now, seems run correctly but only when mounts the root . When I want to use the other image, the init process return an error when reading the config text file. Sometimes, it return also an out of space memory error! Is the standard init process using the entire amount of memory to run (2MB)? I think it can be a problem due of my HW!!!!..... With the , when I run application more larger than os utilities, system crash as before I explain. For me the problem is on the A20 gate handling. I try to initialize it in assembly code as there's in the 2.2.20 linux official kernel but nothing change. In my embedded system are there any difference (memory mapping ecc.) from standard implementation of ELKS?? In boot kernel retrieve > ... 637 Kb base memory and 1024Kb extended memory.... How do I debug this kernel on my system? is there any standard solution or must I to insert puts() for everywhere? If anyone has a good idea, please send it to list........ thanx at all! teo_icKs ______________________________________________________________________ Mio Yahoo!: personalizza Yahoo! come piace a te http://it.yahoo.com/mail_it/foot/?http://it.my.yahoo.com/
