Getting into the bootloader mode if they removed the up , down , select buttons


#1

Hi,

Our pcb guys sent me a prototype with the EMX on it but didn’t provide the up down select buttons, is there a way other than using those buttons to get in to the bootloader mode so I can update the GHI firmware?


#2

Yes, see manual please. I think it is $ sign


#3

ok I’ll have a look, thnx!

For others searching this

[quote]EMX provides an emergency direct access to the
GHI boot loader through COM1 which can be done
by sending the % character continuously and
quickly to COM1 on power up from terminal service
software (TeraTerm) with the following settings:
• Baud rate: 115200
• Bus width: 8 bits
• Parity: none
• Stop bits: 1 bit
• Flow Control: none[/quote]

Hmm… I’ve been trying this method (sending % every 500ms) as soon as the power is on… but it does not seem to have any effect


#6

Why 500ms? send it faster


#7

For things like this I hold the required key down in the terminal program and then power on the device.


#8

Tried Jeff’s method using TerraTerm and tried the no delay method with eltima serial port monitor… the managed application still boots

Just remembered this is not a Panda
