I am looking for a tool to facilitate maintenance of a firmware-based product, but I don't know whether it exists, nor do I have a name for it. Ideally it would be vendor agnostic as I never wish to be covenant-married to any particular processor, language, or IDE. I will illustrate a typical problem (greatly simplified) from a real-life example. Let's say my executable comes from 2 sou...

Hi, New member here so hopefully I am in the correct group. We have many controller boards in the field running the NXP1769 processor. Randomly, maybe a year or even 2 years down the road, the processor crashes and re-flashing the firmware brings it back to life. We know it is a transient doing this but while we are chasing that problem, a stop gap fix would be to come up with an auto re-f...

Hi there, I'm trying to programme a USB to behave like a mass storage device and a network unit (rndis) as the same time (only one usb port), i mean, when i plug it to a windows PC i would like to see two new devices plugged. The only way i've found is to show the usb like a hub with virtual units connected to it, all handled by software. Does anyone knows another way? Thank you!!

I am quite used to playing with PICs and JAL v2. I use the PicKit3 for programming and debugging. Now I want to learn C and AVR. I thought it may be a good idea to do both at the same time.

Now I need a progra...
