2.4.21 MPC8xx Ethernet Fix
Hi I have saw that in kernel 2.4.21 they are a fix for the net driver of mpc8xx. Does Anyone known what this fix is ? Should be may be useful to had it to the next ELDK ?

Motorola finally anounces the MPC5200
That's right.

Hi, Does the current cvs tree of linuxdev on denx past to 2.4.21 ??? I don't have access to cvs here.

RTC for MPC8xx with Linux ?
Hi Personnaly I use a DS1306 on SPI to do RTC on a MPC860. I don't use it under linux still now. But succesfully run it under RTOS. It's port under U-Boot so it's should not be difficult to use it under linux. If someone have some more information about DS1306 under linux (or throught U-Boot may be). If you want to look at the DS1306 U-Boot driver, look at boot/u-boot/rtc/ds1306.c Expects that help Cedric > -Original Message- > From: owner-linuxppc-embedded at lists.linuxppc.org > [mailto:owner-linuxppc-embedded at lists.linuxppc.org]On Behalf Of David > Jander > Sent: Thursday, June 19, 2003 3:37 PM > To: linuxppc-embedded at lists.linuxppc.org > Subject: RTC for MPC8xx with Linux ? > > > > Hi everybody, > > Thanks for all the answers I got over experience with the MPC852T. > One other thing I was investigating is the RTC. > What RTC solutionts are known for easy interfacing with MPC8xx processors, > that work under linux ?

Console problem with linuxppc_dev-2.4.20
Hi, I have succesfully boot linux on my custom board (MPC860) with the Denx 2.4.4 linux kernel with U-Boot 0.3.0. In fact I have porting U-Boot and succesfully boot linux without any port of it (just boot and have stdin, stdout on SMC1, no ethernet, no SCC). I use some configuration in the Denx 2.4.4 linux kernel source. It's the "SMC1 for console" option. The other choice is to use "SMC2 for console" option and it's disable. In the linuxppc_dev-2.4 CVS tree, this option disappear. In look in the uart.c, and I saw that the SMC1 for console wasn't mandatory because it's only test the SMC2 for console option and if it's disable then it's use SMC1. So It's normal that this option disappear because it's never test. But if I try to boot the linuxppc_dev-2.4 kernel nothing happen. I can't test if linux really boot behind because my card it's dommage now so until it will be repair ... But I want to ask to the list if someone had this problem before.

JFFS2 on the Host
Hi, I have read some documentation about jffs2 but I don't find what I want (may be I am to difficult !! :-). I found how configure my flash on the target and by the target. Kernel configuration OK -> Next Eraseall -> mount or make a jffs2 image and cp it before mount it's ok. But How can I make a full Binary Image of my flash partition (good size) on my host and after transfer it on the target at the right place with my loader (u-boot for example) ??

Interdependence of gcc to glibc/linuxheaders?
Hi I am not an expert but I have just build my own gcc last day. I have understand (may be wrong but I don't think :-) that when you build some gcc, you need like you say the kernel headers and a libc. The version of kernel headers option is not very important, the lastest is better but you can build some other kernel version with your gcc. But for the libc, it's different, you will make a choice, if you want uclibc or glibc, your gcc will be make and always use this libc. So if you want to use another libc you had to rebuild your gcc. But another solution you can build your gcc with glibc an after build uclibc with this gcc an you will have a another gcc patched for uclibc for example you will have for glibc powerpc-linux-gcc and for uclibc powerpc-uclibc-gcc. For my self I prefer to build my own uclibc gcc (3.2.2) directely with the uclibc toolchain (very easy to do) Cedric --- Darin.Johnson at nokia.com wrote: > > I notice that during the builds of GCC it requires > linux headers and actually copies headers and > libraries from glibc.
