how to have multiple configurations to boot in picore+

[manit123]

what can be grub2 (of desktop pc) like arrangement here ?
example - i want to be asked at boot which entry i want . all entries will have different  kernel  options .

see the example in the last post of this thread:

i meant , booting of raspberry pi b+ does not involve grub2 or similar boot loader .

No bootloader like grub, it is an embedded system.

You must change config.txt and cmdline.txt either manually or by script (program) and reboot. You can use multiple TCE directories too. I have multiple versions on a single SD card, it works fine.

you can use
'uboot.bin - Third stage: U-Boot loader '
**FreeBSD/ARM on Raspberry Pi is using it !

I would be intrested in "multiple configurations" via some kind of menu (if any one know a way that works, do tell )

From what little i know it might be possible with uboot
But i have thus far been to distracted to setup a test..... 

Anatomy of a Raspberry Pi Boot Image

A FreeBSD bootable image for Raspberry Pi has both FAT and UFS partitions containing the following files:

    FAT Partition
        bootcode.bin - First stage boot
        start.elf - Second stage boot
        config.txt - configuration for start.elf
        rpi.dtb - FDT file loaded via config.txt
        uboot.bin - Third stage: U-Boot loader
        uEnv.txt - configuration file for U-Boot
        ubldr - Fourth stage: FreeBSD bootloader

Hi...

I am in for writing a script, which lets you choose kernel versions, at SSH-login prompt.

I got the main part working, but needs to figure out, howto use multible TCE -dir's (TCE-A, TCE-B etc...)
Havent dig into it yet though!

Any hint Bela' ?

Use tce= command line parameter to specify it explicitely.

uboot: it would be good to have it working with piCore too as an alternative to the manistream booting. I'm busy with the base system and extensions, no time to work on uboot. Contrybutions are highly appreciated!

Use tce= command line parameter to specify it explicitely.

Okay, so i simply use e.g ::

tce=/dev/mmcblk0p2/tce-a smsc95xx.turbo_mode=N dwc_otg.fiq_enable=1 dwc_otg.fiq_fsm_enable=1 dwc_otg.fiq_fsm_mask=0x3 dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 initrd=0xa00000,3787852 root=/dev/ram0 elevator=deadline rootwait nortc loglevel=3 waitusb=5

or "default" ::

tce=/dev/mmcblk0p2/tce smsc95xx.turbo_mode=N dwc_otg.fiq_enable=1 dwc_otg.fiq_fsm_enable=1 dwc_otg.fiq_fsm_mask=0x3 dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 initrd=0xa00000,3787852 root=/dev/ram0 elevator=deadline rootwait nortc loglevel=3 waitusb=5

well i try it out !

[bmarkus]

By default no hardwired tce directory, system is searching mountable fat and ext partions for /tce and uses the first found. Same as on x86

Multible questions then ::

1/ If i use more than one tce-dir, then i can set in cmdline.txt tce=/dev/mmcblk0p2/tce-a for boot into eg. kernel a - Will it work for default location like tce=/dev/mmcblk0p2/tce

2/ Do i then have to make persist in /opt/.filetool.lst eg. dev/mmcblk0p2/tce-a ?

Okay... enough for a start!

1) Yes

2) No, /mnt/mmcblk0p2 is the 2nd partition of your SD card which is persistent

bmarkus ,
please ,  can you show your config.txt & cmdline.txt ?

Just the default with tce boot code, nothing special.

Hi...

I have been trying, without luck, to paste the tce=/dev/mmcblk0p2/tce, RPI boots, but no ethernet

Whats the right syntax

Code: [Select]

tce=/dev/mmcblk0p2/tce smsc95xx.turbo_mode=N dwc_otg.fiq_enable=1 dwc_otg.fiq_fsm_enable=1 dwc_otg.fiq_fsm_mask=0x3 dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 initrd=0xa00000,3787852 root=/dev/ram0 elevator=deadline rootwait nortc loglevel=3 waitusb=5
