[mc1322x] New to the list and Freescale CPUs - firmware loading question

[Daniel Berenguer]

Hi Barry,

The MC13224 has a UART/SPI/I2C bootloader by default so you can
program a new blank uC through serial if you want. Apart from that,
the MC13224 has a JTAG interface too. The econotag provides an USB
interface in order to program the uC serially or through JTAG. No
other hardware needed.

Daniel.
