Subject: RE: [ECOS] Reboot flashing from eCos system?
Date: Tue, 16 Aug 2005 07:27:00 -0000 [thread overview]
Message-ID: <B573B0465A4EFB42997BADDC2FBDE1547ADD97@ples506a.stcl.siemens.co.uk> (raw)
Hi, I have done this. And it works very well (no problems so far!!).
I load a flash based version of redboot via TFTP or from the filesystem
into ram. I then disable interrupts and use the eCos version of the
flash programming functions (not the redboot ones), to program the first
section of flash with redboot. Note that the flash programming functions
must not use any redboot virtual vector functions (mine don't). You need
to then reboot.
I have not found a way of making this fail-safe, once you start the
upgrade you cannot stop. However you could make a copy of the original
redboot image and write it back if something failed.

Subject: [ECOS] Reboot flashing from eCos system?
Hi,
Is it possible to re-flash reboot from a running ecos system? I need to
flash a whole system (inclusive reboot) for production, but i'm not sure
if
i can flash reboot besides the normal system (ecos and configs).
Bye...
