K64F bootloader version at 0202?

Hello,

According to the link: http://mbed.org/handbook/Firmware-FRDM-K64F , the bootloader firmware should be at 0202. After upgrading, the bootloader seems to still be at 0201. In fact, all 3 bootloader .bin files that are associated with the link show the same result. Are we at 0202 or 0201?

Contents of bootloader.html after upgrade to 0202:

I figured it out Sam,

Once you upgrade, then reboot as a BOOTLOADER drive, the html file says 0201. If you come up as an MBED drive, the html file says 0202. So there is just a simple documentation error in the bootloader's html file.

Now back to figuring out my EthernetInterface init() issue.....

I just looked at the binary and the htm part of the file says 0202. Can you try this link? http://mbed.org/media/uploads/sam_grove/k20dx128_k64f_if_mbed.bin

Make sure to press and hold the reset button before and while connecting USB to init the bootloader. The drive will be named BOOTLOADER, not MBED when ready for this file.

Accepted Answer

Looks the same Sam,

Maybe it is 0202 and the html file is mis-stating the facts.

Here is the html file :

2 questions

  1. Are you dropping this binary file on a drive called BOOTLOADER
  2. What computer are you using? This bootloader only works on Windows and Linux
