Dit is iets wat vaak over het hoofd geziien word het eerste uur

Many thanks. Serial sounds good. I used to flash Cisco routers in the past over serial. Can I connect the RX TX GND directly to serial or I need a converter to USB? Once connected over serial, I presume that it loads the image over tftp right? Got some hopes.Petervanakelyen schreef:You can reflash the firmware using serial or JTAG.

As you can see in this picture, it seems to be neccessary to use an USB converter. You can make one yourself using a MAX232 as honda4life suggests. Flashing the firmware is probably done over TFTP as you already presumed.adis schreef:Many thanks. Serial sounds good. I used to flash Cisco routers in the past over serial.

I don't think so. Shouldn't be there some flash memory on the USB converter board in that case? Most of the time you just use HyperTerminal/any of the linux serial consoles to start a TFTP client that loads up the configuration from the TFTP server in the network.I think you copy your files to a temp directory from usb drive (formatted as ext because of linux kernel), and flash it then.
Sinds ongeveer een week loopt ZTC (Zero Touch Configuration) nu wel op Scarlet lijnen, onafhankelijk van de firmware.redman schreef:Ook al zet je de belgacom firmware om de scarlet box, de zero touch zal nooit lopen op een scarlet lijn.
Het kan wel zijn dat je een nieuwe firmware binnen haalt, maar dat is iets anders dan de zero touch.
idd, sagem boot gewoon met de img van de tftp server, het staat ook in mijn uitleg dat je na het booten van tftpAh, dus die recovery procedure vervangt de huidige firmware niet, maar start eenmalig op met de firmware van de tftp server, dit verklaart waarom een reboot telkens opnieuw de sagem box deed vastlopen.
Wss was het bij jou een factory reset genoeg geweest. Bij mij wou v. 42 echt niet werken, 40 doet het wel goed, heeft iemand een linkje voor 46?- surf to the IP of sagem (the one it got from the dhcp server)
- flash as usual

Recently I've tried to flash the BGC fw and "bricked" the sagem, it seemed that my sagem doesn't like 60A042. After a bit fiddling I found out that one can recover from a bad flash w/o resorting to JTAG as long as you have a good recovery image.
Thing that you need:
- a dhcp server
- a tftp server
- s sniffer (tcpdump wireshark)
- some common sense
how this works? Booting in recovery mode and samgem will get an IP from dhcp server then do a netboot/etherboot and download the image from tftp server, then you can access the web/telnet interface again then reflash with a good image, that's it.
Step by step howto:
- start a sniffer
- boot the samgem in recovery mode by pressing the reset button and power on
- you will see that it asks an IP and should get it from the dhcp server
- you will see that it tries to download a file from an IP (write down this IP as tftp server) with a path (write it down) and filename (write it down)
- give your tftp server the IP address that you wrote
- rename the FAST3464_<whatever> to the filename you wrote and move it to the direcoty (relative to your tftp root) path that you wrote
- reboot the sagem in recovery
- surf to the IP of sagem (the one it got from the dhcp server)
- flash as usual
- done
As said earlier you need to find a good image, my sagem doesn't like 60A042 no matter what I do, but 60A040 works like a charm.
