Puya PY32F MCU support (#5106)
* pinout yamls removed * machine: implement default UART pin configuration for Embedfire boards * flash command moved to chip level so VS Code plugin can select bare chip * machine: add support for alternate pin mode configuration * add build targets for embedfire on py32 * add support for embedfire target in GNUmakefile for py32 * lib/py32-svd: remove duplicate DBGMCU.IDCODE CODE field Update submodule to fix duplicate SetIDCODE/GetIDCODE method declarations in the generated py32f002bxx.go device file. * update subproject commit reference in py32-svd * refactor: update CPU frequency handling in machine and runtime packages * refactor: replace ConfigureUARTPin function with direct pin configuration in UART setup * SetAltFunc documentation for GPIO pin alternate functions * refactor: improve UART write and flush error handling with timeout * machine/py32: generalize UART driver to any USART Add a per-instance setup func to the UART type so the driver is no longer hardwired to USART1. DefaultUART stays USART1; add UART2 (USART2) in a separately build-tagged file since py32f002x parts lack USART2. RX IRQ handlers reference runtime-assigned vars to break the init cycle, and setup is assigned in the var initializer so it runs before InitSerial. Add the py32f003_32k_4k target (32K flash / 4K RAM). * Add canonical PY32F002, F003, and F030 density targets Use CMSIS/pyocd device names for target files and build tags. Add all F003 and F030 densities plus F002A/B, correct F002B to 24K flash and its own startup file, fix the F030x8 pyocd target, and update Embedfire inheritance. * Add targets for all PY32 CMSIS devices * Support all PY32 register layout variants * machine/py32: use generated register definitions * machine/py32: fix alternate-function documentation * machine/py32: report the configured CPU frequency * machine/py32: use unsafe.Add for GPIO ports * machine/py32: bound and yield UART polling * machine/py32: configure UART pins from UARTConfig * build: use the current PY32 SVD repository URL * test: cover PY32 UART register layouts * machine/py32: restore dynamic CPU frequency tracking * machine/py32: share the USART TX-ready bit * targets/py32: scale system stacks with RAM * machine/py32: keep clock state internal * targets/py32: normalize generated metadata * machine/py32: normalize GPIO configuration * machine/py32: fix T020 UART setup * machine/py32: reduce clock variant files * machine/py32: clean up UART variants * machine/py32: decouple UART clock capability * lib/py32-svd: use organization repository * runtime/py32: name 24MHz HSI encodings * machine/py32: derive startup clock from capability * machine/py32: use generated USART clock mask * machine/py32: name T020 8-bit UART mode * ci: include PY32 in sharded smoke tests * runtime: remove PY32 HSI frequency workaround

# PY32 target generator
|
||||
|
||||
This command generates TinyGo target JSON and linker scripts for Puya PY32
|
||||
microcontrollers. Run it from the repository root:
|
||||
|
||||
```sh
|
||||
make gen-target-py32
|
||||
```
|
||||
|
||||
The normalized [device table](devices.csv) was derived from the `<device>` and
|
||||
`<variant>` leaves in the official Puya CMSIS-Pack PDSC files. Memory values are
|
||||
the inherited default `IROM1` and `IRAM1` regions. The three PY32E407 parts have
|
||||
multiple adjacent default RAM regions; their linker definitions combine those
|
||||
regions into one contiguous RAM range.
|
||||
|
||||
The table contains 87 concrete devices associated with 40 SVD families. The
|
||||
pack also supplies `PY32F001xx.svd` without a corresponding PDSC device, so the
|
||||
generator creates its family target but cannot create a concrete memory target.
|
||||
Together these inputs produce family targets for all 41 available SVDs.
|
||||
|
||||
Cortex-M0+ families inherit `py32`; PY32E407, PY32F403, and PY32F410 families
|
||||
inherit `py32-m4`, which uses TinyGo's standard soft-float Cortex-M4 ABI. Targets
|
||||
whose SVD has no `GPIO.AFRH` register receive the `py32_no_gpio_afrh` build tag.
|
||||
|
||||
Puya's SVDs are inconsistent about GPIO `groupName`: some describe identical
|
||||
ports as `GPIOA_Type`, `GPIOB_Type`, and so on, while others use one
|
||||
`GPIO_Type`. The `py32-svd` updater validates the register structures and
|
||||
patches the published SVDs to use the common `GPIO` group. This is a correction
|
||||
to the vendor metadata, not a target capability, so neither TinyGo's generic
|
||||
SVD generator nor the target build tags need PY32-specific handling for it.
|
||||
|
||||
Real register-layout differences are selected by generated capability tags.
|
||||
These cover the `OSPEEDR`/`OSPDDER` GPIO spelling, RCC GPIO and UART clock
|
||||
registers, `USART` versus `UART` blocks, split USART receive/transmit data
|
||||
registers, and HSI selector availability. Keep these classifications in the
|
||||
target generator rather than adding long family expressions to machine files.
|
||||
|
||||
All concrete target JSON files and linker scripts are generated so inheritance,
|
||||
memory definitions, and stack sizes remain consistent. Verified flashing
|
||||
commands are preserved in the generator; other targets omit them until a
|
||||
compatible programmer identifier is known.
|
||||
|
||||
The system and interrupt stack is sized from available RAM: targets with up to
|
||||
4 KiB use 1 KiB, targets with up to 16 KiB use 2 KiB, and larger targets use
|
||||
4 KiB. This linker-defined stack is distinct from goroutine fallback stacks
|
||||
selected by TinyGo's `--stack-size` option.
|
||||
|
||||
## Machine support status
|
||||
|
||||
A minimal program compiles for all 87 concrete targets. GPIO, RCC, runtime
|
||||
clock setup, and the default serial block are selected according to each SVD's
|
||||
register layout. This is compile-time coverage, not hardware validation for
|
||||
every device. In particular, PY32F410 SVD interrupt metadata stops before the
|
||||
serial interrupts, so its default USART is configured without receive
|
||||
interrupts rather than assigning an unverified IRQ number. The M4 SVDs also do
|
||||
not expose the M0+ `ICSCR.HSI_FS` selector, so the runtime preserves their reset
|
||||
clock configuration and initially reports the vendor-defined 8 MHz reset
|
||||
frequency. Custom clock HALs must update TinyGo's internal clock state, then
|
||||
reconfigure SysTick and frequency-dependent peripherals.
