Question about updating an old eCos driver


Hi,

3 years ago, we developped a CAN Driver for our board using an old eCosPRO
(2.032).
Then we had some interrupt problems and now, we want to use the last eCos
to test if the interrupt problem exist yet.
I made some tests and I have an other big problems which is the call time
of the POSIX read function:
With the old eCosPRO, it tooks 25µs and with the eCos from last week, it
tooks 200µs for the same call read function. And so the DSR takes too many
time to be executed.
This let me think that eCosPRO (1.032) and this ecos kernels are very
different.

Does Driver initialisation system changed from eCosPRO (2.032) to the last
week eCos version ?
Do we have to change something in the Configtool ?

Thank you,

Emmanuel Coullien
