-- Infineon XMC4500 Relax boot-kit build configuration
|
|
|
|
--[[
|
|
|
|
Notes:
|
|
|
|
1) The XMC4500 has its own SDMMC peripheral. So, we won't go the
|
|
regular SPI way to talk to the SD card. This also frees up an
|
|
additional USIC (configured as SPI) channel. At the moment, spi,
|
|
cs_port and cs_pin are set to 0. Perhaps there is another way
|
|
to override this requirement?
|
|
|
|
2) This point is specific to the Relax kit:
|
|
|
|
When the Relax board is plugged into a machine, it will not get
|
|
enumerated as a Jlink virtual COM device (OR a ttyACM0) like the
|
|
Hexagon. I presume this has something to do with the Jlink VCOM
|
|
firmware used on the other XMC4500 at the debug port of the kit.
|
|
|
|
I use a Silicon Labs CP210x USB to UART bridge to interact with
|
|
eLua. Simply connect the bridge to the pin-outs on the boot-kit.
|
|
UART RX is Pin 1.4, and TX is Pin 1.5. [An Adafruit's FTDI friend
|
|
might work equally well].
|
|
|
|
Otherwise, the chip is exactly the same as the one used on the
|
|
Hexagon board. Enjoy eLua!
