Re: OTA support and SPI Flash usage

Good news is bootloader & partition table is all open source. So you can customize it to your needs.

Re: new uart driver and acessing flash boots the system

No I mean why are you erasing the flash every time UART data is received? Trying to kill that sector?

mDNS sounds good, and throw in uPnP and NBNS while you're at it :)
