Hi

The SDHC port is not yet supported - this is something which is however very interesting in the Kinetis K60 and so it is a point that will probably get solved shortly (note also that wireless LAN interfaces are increasingly popular in SD card format and SDHC interface so this is a further point that makes SDHC even more interesting.

USB driver code is inlcuded but it hasn't been tested yet. It seems to be essentially compatible with the M522XX USB (although has some additional features) and doesn't need to swap USB pointers between little-and big-endian mode - note that the M522XX is big-endian but its USB controller works with little-endian pointers.

Furthermore, the Kinetis has a different SPI interface (not QSPI) and so also SD card will not work without adapting this port. Thsi shoudln't be a big job though since basic SPI operation is usually quite simple.

Regards

Hi

Update: I have now a working version of the utFAT using the SDHC controller in the Kinetis.
I still need to integrate the SDHC controller model into the Kinetis simulator (not a big job but needs to be done before fully completed) and then it will be included in the next development version.
