Something we are currently doing with a EP7212 board, is to compile the
library lib7209 whose
source C files are available from the Cirrus Logic CDROM (Maverick arm
SDT environment),
with the arm-elf-gcc cross-compiler. All LCD functions (sensitive
touching, graphical and text display)
run correctly. All you have to do if you intend to use these functions
in a multithreaded application,
is to protect areas where physical ressources are accessed (e.g. memory
read/write,...) with eCos
mutex mechanism. You can find some posts exchanged from the mailing list
archive under
subject: "eCos EDB72XX lcd driver library" or "EDB7212 LCD support".
