LPC2xxx / Re: Slower baudrates communication (autobaud)

Thank you, Andy for fast and professional responces, it is pleasure to meet such high level of support.

Issue was in opto-isolator of my USB-UART, it worked almost fine, but slightly affected first byte only.

It's FTDI based converter and it works fine with the same board and default firmware.
Even on 7812bps (9600*12/14.7456) because default 14.7456MHz oscillator was replaced with 12MHz

I understand that it's not flash magic issue, but default firmware works ok and 12MHz oscillator seems also starting.
Thats why I want to flash it with 12Mhz RedBoot and forget about onchip bootloader.

LPC2xxx / Slower baudrates communication (autobaud)
« on: August 03, 2017, 10:04:41 pm »
I'm trying to connect to Olimex LPC-H2294 (rev A) with 12MHz oscillator

With terminal programm I could see answer to "?" (Synchronized) only on 300baud.
It is strange, but I realy want to flash device even if it'll take an hour.
Is it any way to connect on lower speed than 2400?

And another question about "oscillator" value, what it is used for in my case (autobaud), is it used at all, or mostly for another CPUs?
