Can't change frequency during FW update process

[Arnaud]

Hi all,
I'm trying to update my MD FW from 20120415 version to 20131111 but without success because during the update process it's not possible to change the frequency to 20MHz by pressing the "UP" button then the FW flashing fails indicating a "CRC error" in the terminal.
For information i'm under MAC OS 10.6.8, the megadrum is a Atmega and i'm using MDM 20140201.

Does the wrong frequency (16MHz instead of 20MHz) can cause this kind of error?
What would be the reason to cannot be able to change the frequency?
If somebody have an idea... feel free!

Thanks!

What has changed between viewtopic.php?p=21304#p21304 and now that prevents you from selecting 20MHz? Maybe button UP is not working? If it's not set to 20MHz in the bootloader, it will fail.

Hi Dimitri,

Thanks for your feedback.
Last time , i was not following the process correctly. Now i know the FW update process but can't change the frequency. I will double check if the "UP" button is working properly but it seems that it is.
By the way , is there any other way to change the frequency?

Only with the button UP.
