Wolfgang, This patch and running dhcp from preboot does work as expected. Is this a change that should be put back?
Another question on this topic, what is the general strategy on auto-updates. If I leave the .itb file on the tftpserver an update will occur on every reboot. Is there a way to check any version info from the .itb or uboot file to know if I am already at the uboot version in the .itb file and then not attempt the flash update?

But you can try to apply this patch, and then run the "dhcp" command from your "preboot" settings: diff --git a/common/main.c b/common/main.c index 10d8904..c860b0b 100644 --- a/common/main.c +++ b/common/main.c @@ -305,10 +305,6 @@ void main_loop (void) trab_vfd (bmp); #endif /* CONFIG_VFD && VFD_TEST_LOGO */ -#if defined(CONFIG_UPDATE_TFTP) - update_tftp (); -#endif /* CONFIG_UPDATE_TFTP */ - #ifdef CONFIG_BOOTCOUNT_LIMIT bootcount = bootcount_load(); bootcount++; @@ -369,6 +365,10 @@ void main_loop (void) } #endif /* CONFIG_PREBOOT */ +#if defined(CONFIG_UPDATE_TFTP) + update_tftp (); +#endif /* CONFIG_UPDATE_TFTP */ + #if defined(CONFIG_BOOTDELAY) && (CONFIG_BOOTDELAY >= 0) s = getenv ("bootdelay"); bootdelay = s ?
