Hi,
oke, I will file a bug tomorrow.. this was one hell of a debugging
session since last friday (60+h).
It seems to be a general problem with arrays. I found another (probably
similar) problem with this line of code :
TXREG = uart_start_condition[uart_tx_start_condition_index++];
Here uart_tx_start_condition_index won't be incremented.
I'll check the assembly code tomorrow, because i don't have internet on
my laptop in linux (my mate-desktop decided to disable the
wlan-connection for today...).
Cheers,
Oli

We are missing a banksel before the decf instruction (i. e., we should
expect to have banksel _ep_bdt+9 instead of the movff instruction).
That is obviously a bug. Please consider filing this work the bug
tracker so it does not get lost.

For one "really bad in assembly" you managed to pin point the problem
rather well - impressive ;-).

No, not this time.
Kind regards,
