[Elecraft] Fwd: K3 Failed DSP Firmware Download

[ab2tc]

Hi all,

I have loaded virtually every firmware version that ever came out without a
single incident, using several different USB adapters (never had a real
serial port with the K3) and several computers. So I don't have problem with
this at all. With this said, it does appear that a few things could be
improved when there *is* a problem with the communications. The idea of
testing the serial communications before committing to the update is a good
one. Also it does seem that the utility could be improved in it's ability to
recover from errors and give more meaningful messages to the users.
Bootloaders are inherently dumb and they need to be in order to keep them
small. To expect it to be able to cope with "unexpected" commands is simply
expecting too much.

PS. The PIC processor with 128kb of flash and 4kB of RAM, oboy that seems
like a flashback to another century to me. I am amazed at the Elecraft
programmers being able to cram the current functionality into this extremely
limited space.
