KL27 rom-bootloader too slow!

[paolocolombo]

Hi to all,

I'm using rom-bootloader on KL27Z256 on USB. It works corretly, but I think that it's too slow.

In fact, to program 52Kbyte software takes 3 minutes and 15 seconds!

Communication seems to be OK: USB packets travel at 5MHz, and see a package every 1ms. What's the problem then?

It is correct that it is so slow?

Thanks, to all.!

Hello Paolo Colombo:

This is a problem with the HID USB bootloader. The new release of KBOOT (v1.2) is estimated to be released this week and the problem will be fixed already.

Regards!
