Hi, I use board DK20K200E with NIOS, 64MB SDRAM module and CS8900. U-boot was get today (29-08-2005) from CVS.
I create gziped standalone images of kernel (2.4) and romfs. I use autoscript to load it from tftp server. The script is put on tftp server and downloaded after obtained ip address by dhcp.
The script correctly downloads both images and put in right place in memory. "iminfo" shows that CRC is correct for both images. But "bootm" show an error -4 Z_MEM_ERROR() in inflate() function.
I set "unc_len" to 0x800000. It's enough for kernel and romfs.
From /include/configs/20K200E.h:
#define CFG_MALLOC_LEN (CFG_ENV_SIZE + 10240*1024)
Size of uncompressed: romfs image: 4965376 bytes, kernel image: 1044480 bytes.
But the problem disappears when I remove "bootm" from autoscript. And run: "bootm 5100000 5400000" by hand in console after downloading images by the script. The kernel boots and mounts romfs.
Below I put autoscript and log of deflating images.
Best Regards, Maciej Witaszek
