#113085 - DS89C420 Bootloader issues
Hello,

I'am using Maxim DS89C420 with few integrated circuits added (RS232A and HC125) as described inside Dallas Semiconductors Bootloader application notes.

http://www.maxim-ic.com/appnotes....umber/3262

It's impossible to me to obtain the communication with the device using MTK loader software and with a 11.052MHz frequency.

/EA, /PSEN and RST are following the "loader" required states but nothing is displayed on the terminal coming from the device.

Please can you help?
Thanks in advance.
