Did anyone get the bzip2 compression working for an 8245 processor?
I think I am having a bit of a problem here :-/
I changed the board configuration to include the following
#define CFG_MONITOR_LEN 0x00030000 #define CFG_MONITOR_BASE TEXT_BASE #define CFG_INIT_RAM_ADDR CFG_SDRAM_BASE + CFG_MONITOR_LEN #define CFG_INIT_RAM_END 0x2F00 #define CFG_GBL_DATA_SIZE 128 #define CFG_GBL_DATA_OFFSET (CFG_INIT_RAM_END - CFG_GBL_DATA_SIZE) #define CFG_INIT_SP_OFFSET CFG_GBL_DATA_OFFSET
(copied from another 8245 board) and set #define CONFIG_BZIP2
I also set the size of the MALLOC section to
#ifdef CONFIG_BZIP2 #define CFG_MALLOC_LEN ( 2500 * 1024) #else #define CFG_MALLOC_LEN (512 << 10) #endif
Even though my requested malloc size (2500) falls in the 12M (CFG_INIT_RAM_END), booting a gzip compressed file works fine; while a dump after trying to boot a bzip2 compressed file shows nothing (memory is empty).
The same with 4 MB (unless I am mistaking, the 'slower' alg bzip2 algorithm works?).
I am certain that I am doing something stupid :) but still, ... Any pointers?
Btw, I need the bzip2 compression because I only get 768 M in the kernel partition and repartitioning the flash would break backwards compatiblity.
The 2.6.7 kernel jumped to some 800 M (up from 550 or so when compared to the 2.4.24). After all the warm encouragements over the last weeks towards the 2.6; I decided to take the jump :)
