#123807 - Need a better protocol! Responding to: ???'s previous message |
Kelvin Yan said:
I have discovered that the IAP actually crash the system, when the serial interrupt occured, during the IAP write operation. Allowing interrupts while actually updating the flash sounds like a really bad idea in any case! I can't predict the time to receive serial data True, but you can disable the interrupt. This may cause you to miss data - so you need to ensure that your protocol can detect this, and retransmit. Alternatively, redesign the protocol so that you can predict when serial data will arrive! |
