This fixes some missing and incorrectly-assigned pins for the SparkFun Thing Plus RP2040 protoboard so that they actually match what the board says. This also changes the default SPI pins from the SD card pins to the breakout pins on the side of the board.
When `reload_requested` is detected, the run reason will no longer be
automatically overwritten as an AUTO_RELOAD, making SUPERVISOR_RELOAD a
detectable reload reason. Autoreload now sets the reload reason itself.
Added board definition for the Sparkfun MicroMod RP2040.
Mostly followed the format for pins from the MicroMod nRF52840 board
definition, as MicroMod tries to standardize pins across
microcontrollers.
This update to the PR retains the earlier board rev (with a rename) so
that backward binary compatibility is not lost for the earlier board
revision. The primary name 'vina-d51' is retained for the latest
revision to make it easy for customers to select the proper UF2
download - because the name matches the commercial name.
Details:
Replace bdmicro_vina_d51 with bdmicro_vina_d51_pcb7 (revision 7 of
PCB) with boardfiles unmodified. Add _pcb7 to the workflow build.
Replace bdmicro_vina_d51 boardfile content with latest PCB updates
(revision 10 ov PCB). Add minimal comments in the board files to make
it clear which PCB revision is implemented. Update the USB PID to
reflect an updated board revision.
ESP-01 header renamed to AUX, and expanded to 12 pins from 8
pins. Pins 1-8 still accommodate the ESP-01, with expansion to full
SERCOM 4-pad support to allow for SPI and I2C on that expansion port
with additional GPIO control.
Update pins.c with additional signals provided AUX_1-8, along with
UART, SPI, I2C name usage as aliases to appropriate AUX_1-8
signals. Additionally, add several alternate names specific to several
expansion modules - the ESP-01, and the ATW-01 using the WINC_1500
(SPI) w/interrupt and control needed for the WINC - with assignments
to module pin positions.
Re-work SERCOM assignments to accommodate the above from other parts
of the board, which required moving a SERCOM or two around in order to
accommodate the 4-pad sercom pin mapping on the AUX port.
