It's a trade off - do you prevent interrupts (hence ISR routines) from
running during all data critical sections or do you simply not allow
those [ISR] functions to execute code that might perturb critical data?
eCos chooses the latter method which allows for lower interrupt latency

Normally, you try not to disable interrupts in RTOS's. You should
protect your critical regions with mutex's, semaphores etc.
I remember well that I(we in our company) have used intLock () in VxWorks to
make sure that interrupt doesnt during some critical sections. Ofcourse we
did use
Hi Ram;
I checked on Port B there's nothing coming out. The setup is :I have
Port A connected to one machine from which I upload the application
(bin_sim0) and port B connected to some other machine to see if
anything comes out. From both machines nothing comes out. But if the

I am puzzling over how the eCos flash drivers are supposed to work when
using 16-bit wide flash devices. I'm using an ARM architecture (ARM7TDMI,
ARM940T), and the AMD AM29LV160 flash device connected in the 16-bit wide
mode (CYGNUM_FLASH_WIDTH=16).
Looking at the flash driver code, this defines
