Ok, now I've tried the kernel that you made for some other board (http://www.rtp-net.org/ss4000e/zImage_2633_iop32x_defconfig), and it appears to nearly work, but not quite. I get past the Uncompressing Linux bit, to "done, booting the kernel.", and then it starts giving me garbage characters, as though it doesn't understand the rate of the serial port. My session looks like this: RedBoot> load -r -v -b 0x00180000 zImage_2633_iop32x_defconfig Using default protocol (TFTP) / Raw file loaded 0x00180000-0x003f1aaf, assumed entry at 0x00180000 RedBoot> exec -c "console=ttyS0,115200n8" Using base address 0x00180000 and length 0x00271ab0 The boot tags are located at 0xA0000100 Booting the kernel... Uncompressing Linux... done, booting the kernel. �9H8 {.) ( +�.��0P 88)� (q.y.P� (.(.9y �(.qR蕚�( �(((.(HO ��.(.* I did set the rate on the serial port when booting, so I don't know if it's somehow using the wrong driver for the serial port it's attached to, or if I'm somehow setting the rate wrong. I'll keep playing with it anyhow, and see what I can come up with. Any suggestions would be welcome, of course. Also, that final line keeps changing, so there is output being written to the terminal, it's just invalid output. I think that kernel can boot my hardware, if only I could get a reasonable output from it. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
