As u said, the problem was with the RTS/CTS. I disabled all the hardware control signals and some modifications with the relocation section in the start..S and it started working.<br><br>Now the issue is with the kernel CRC32 check. I compiled a kernel with the smdk2440 architecture and I do the following.<br><br>$ arm-linux-objcopy -O binary -R .note -R .comment -S vmlinux linux.bin<br>$ gzip -9 linux.bin<br>$
../u-boot-1.3.2/tools/mkimage -A arm -O linux -T kernel -C gzip -a
0x30008000 -e 0x30008000 -n "Linux kernel" -d linux.bin.gz uImage.bin<br><br>The size of vmlinux is around 25MB. When converted to linux.bin it is 3GB, when gziped it is around 4MB and when done an mkimage it remains almost the same.<br><br>The output is as follows:<br><br>U-Boot 1.3.2 (Apr 7 2008 - 12:14:29)<br><br>DRAM: 128 MB<br>Flash: 32 MB<br>Using default environment<br><br>In: serial<br>Out: serial<br>Err: serial<br>Hit any key to stop autoboot: 0<br>## Booting image at 33000000 ...<br> Image Name: Linux kernel<br> Image Type: ARM Linux Kernel Image (gzip compressed)<br> Data Size: 4271633 Bytes = 4.1 MB<br> Load Address: 30008000<br> Entry Point: 30008000<br> Verifying Checksum ... Bad Data CRC<br><br>What ever kernel image I load it tells the same ie. "Verifying
Checksum ... Bad Data CRC". I even tried the uImage.bin which was available on openmoko site and the same error occurs.<br><br>Is the error with the bootloader or the kernel image? If so what are the changes to be done?<br><br>Thanks in advance.<br>Tiju<br></div></div><br>
