Re: [ECOS] Re: Linux synthetic target build errors

Thank you, thank you, thank you!

I was able to successfully run your server.elf, which lead me to look
at your newtree-pc_8139.sh
(http://www.panix.com/~grante/files/ecos/newtree-pc_8139.sh)

I noticed that in your shell script, the "cdl_option CYG_HAL_STARTUP
{user_value GRUB}" where as my configuration that was generated using
the default i386 template had the the Startup Type (eCos HAL\i386
architecture\i386 PC Target\Startup type) as RAM". I changed this to
GRUB, rebuild my libraries (Build>Library), rebuild my hello.c
application and that did the trick. I was able to run the runit.sh
file and get QEMU to boot and execute my hello world application.

Now to get some real work done with eCos!

Thank you!
