So there must be another reason it did not work. Does this patch work? It is against current gcc branch. The gcc branch should build fine on IAR as well, otherwise I would like to fix it!

I tested on IAR 4.0 with calling the reset vector rather than a hardcoded assembly branch instruction and it woks as expected.

One issue with the proposed patch however is the following:

-__APP_Start ;void __APP_Start(void)

• B 0x0800C121

If you remove those lines, addresses for callback from APP back into LIB will be incorrect. You should be able to start APP, but as soon as you call back into LIB (such as GetFonts) it is likely to fail miserably unless you adjust the vectors in APP accordingly.

Thanks for looking at it! I originally thought these two lines only defined an __APP_Start() function (jumping to 0x0800C121, and I could just remove it since we do not use it (with the patch applied). But I understand the removal of this code will shift the following code a few bytes backwards… I should replace it with a dummy branch or enough NOPs. It is ugly in any case.
