Re: [seL4] CAmkES parsing issue

      Have you tried moving the import statements above the UART component definition?

In fact, I do not have such a file. My assembly looks like this (see below). I connect the hardware component UART to the Cons_PingMe. So, I do not have any driver defined in a separate file. This is the uart_mem connection that is the issue.
I am almost sure I missed something and not sure this is a bug.

Perhaps you need to add:
import "components/drv/Driver.camkes";
Also Driver.camkes seems to be a copy of ConsumerThreadImpl.camkes and
does not contain a definition of the UART component.

Hi,
I am trying to build a camked application with a UART driver. When trying to
build the application, I got the following error:
While rendering uart_mem.from.source: 'drv'
However, the component is well define. How can I try to get more
information/debug of the camkes assembly and find out what is wrong?
Thanks!
