Where are the old firmwares?

Hi,

I updated my old (one of the first) mbed LPC1768 to the latest firmware 141212 before trying it with a test program running on the PC that communicates over the USB serial port with the mbed module (I did not try the tests before upgrading the firmware). Unfortunately, this does not work properly, sometimes it works for a few bytes, then it stalls. Strangely enough, the mbed USB serial port works fine when I control it manually (typing commands) over USB from a serial terminal like Tera Term. Changing the USB cable does not help. The mbed module seems to be in perfect working order as far as I can tell.

Another (more recent) mbed LPC1768 was given to me to try in the same setup and it works perfectly fine. It has the firmware 16457 on it. Now I would like to try the first mbed with this same firmware, but I cannot find it. Where can I download the old firmwares? Is there a way to recover it from the mbed module itself?

Thanks, Clemens

For completeness sake, reverting yo the 16457 firmware did not solve the problem. I guess my old module is broken somehow.

Hi Clemens, you will find older firmware at the bottom of this page https://developer.mbed.org/handbook/Firmware-LPC1768-LPC11U24

Hi Wim, Can you be more specific? I don't see a link for them, only a changelog. Maybe I need stronger glasses? Thanks

The dots next to the versions (at least for the top 3 ones) are clickable.

You're right, didn't notice those. Thank you!
