Mozart is a motherboard that when paired with a Sechzig compute module can function as a computer.
This repo contains schematics, PCB layouts, pinouts and documentation.
Find more information on the Mozart product page.
Mozart requires a Sechzig module to power on. When inserting a Sechzig module, make sure that pin 2 on Mozart and pin 2 on the module are both on the same side.
Mozart has a JTAG and USB CDC interface that are both accessible on the USB-C port. These interfaces are provided by a fork of pico-dirtyJtag. You can update the RP2040 firmware by holding down the BOOT button and then applying power.
To build the firmware from source:
$ cd firmware/pico-dirtyJtag
$ mkdir build
# if your Mozart has Zetta flash:
$ cmake ..
# or if your Mozart has Adesto flash:
$ cmake .. -DPICO_DEFAULT_BOOT_STAGE2_FILE=/your-pico-sdk-directory/pico-sdk/src/rp2_common/boot_stage2/boot2_generic_03h.S
# then
$ make
Program the configuration SRAM of a Sechzig module:
sudo openFPGALoader -c dirtyJtag image.bit
Program the configuration flash on a Sechzig ML module:
sudo openFPGALoader -f -c dirtyJtag image.bit
Program the configuration flash on a Sechzig MX1 module:
sudo openFPGALoader -c dirtyJtag -f image.bit --fpga-part xc7a35tftg256
See the Kakao Linux repo for the latest instructions.
Mozart has an experimental SATA-style LVDS port. SATA is not supported.
