Q: Bootloader over RS-485 / Modify bootloader?

Started by ateichtmann December 13, 2004


i want to update my application with the bootloader of the LPC2106
over a RS-485 bus. Unfortunately, it is only a half-duplex bus and
the RS-485 driver-ic has to be switched between rx and tx. So my
questions: Does the ISP programs (Philips, other...) and the
bootloader need full-duplex? Is it possible to modify the bootloader
(to switch the RS-485-IC between rx and tx)?
Thanks for all hints...
