Alessandro Gatti	d938d5af4e	qemu/Makefile: Allow usage of a custom QEMU binary to run code. ... This commit introduces a new optional makefile variable to let the build system know that, when running code, a custom QEMU binary must be used instead of the one provided by the system's PATH. Given that the CI machine won't keep up with QEMU updates unless its base image tracks a new version of QEMU itself, sometimes it is needed to use a custom QEMU build to be able to test new code in an emulated context rather than having to perform on-device testing during development.

Alessandro Gatti	cb9d8fcc31	tests/run-tests.py: Discover RV32 extension inlineasm tests. ... This commit extends the test runner to automatically discover inline assembler tests for known RV32 extensions, and checks whether to add the discovered tests to the enabled tests list. Automatic discovery requires that inline assembler tests for RV32 extensions follow a specific pattern both for filenames and for the tests' output in case of success. A valid RV32 extension test must have: * A code fragment that checks for support of the extension on the running target in "/tests/feature_check", called "inlineasm_rv32_<extensionname>.py" that should print the string "rv32_<extensionname>" if the extension is supported * A matching expected result file in "/tests/feature_check" called "inlineasm_rv32_<extensionname>.py.exp" that must contain the string "rv32_<extensionname>" (without quotes) * A regular MicroPython test file in "/tests/inlineasm/rv32" called "asm_ext_<extensionname>.py" For example, to test the Zba extension, there must be a file called "/tests/feature_check/inlineasm_rv32_zba.py" that should print the string "rv32_zba" if the extension is supported, together with a file called "/test/feature_check/inlineasm_rv32_zba.py.exp" that contains the string "rv32_zba" in it, and finally there must be a regular MicroPython test file called "/tests/inlineasm/rv32/asm_ext_zba.py".

Alessandro Gatti	f0895f0ea0	py/emitnative: Optimise register clearing. ... This commit introduces a new generic ASM API function to clear a register (i.e. clearing all the registers' bits). The native emitter used to perform a XOR operation to clear a given register, but different platform have more optimised method to achieve the same result taking up less space - either for the generated code or for the code generator itself. Arm, RV32, X86, and X64 already had an already optimised generator and generated optimised code. The code generator when build for Thumb takes less space generating a constant immediate move rather than a XOR operation, even though both operations would distill down to a single narrow opcode. On Xtensa the situation is almost the same as Thumb, with the exception that a constant immediate move would take one byte less than a XOR operation.

jetpax	e67d4a2a77	esp32/machine_sdcard: Fix SDMMC slot assignment for non-default slots. ... The SDMMC_HOST_DEFAULT() macro sets slot to SDMMC_HOST_SLOT_1, but this was not being overridden when the user specified a different slot number. This caused SDMMC initialization to fail on chips like ESP32-P4 when trying to use slot 0. This commit ensures the slot number passed to the SDCard constructor is properly assigned to the host configuration structure. Tested on ESP32-P4 with SD card on slot 0.

Alessandro Gatti	9c9b99686e	tests/target_wiring: Provide an ESP8266 target wiring module. ... This commit introduces ESP8266 support for target wiring tests, fixing execution of relevant tests that once failed on that platform. ESP8266 boards need to have GPIO4 and GPIO5 connected together to provide a UART loopback, in order to test whether UART data effectively flows through. The wiring-enabled UART transmission timing test was also updated with measurements compatible with a few ESP8266 test boards.

Alessandro Gatti	dbf59db5a1	tests/extmod/vfs_blockdev_invalid.py: Handle low memory conditions. ... This commit modifies the "extmod/vfs_blockdev_invalid" test to better behave on boards with low available memory. Before these changes the test would fail on ESP8266 (at least), due to low memory, but in a way that could not be easily solved as the error occurred in the middle of the test. The test has been rewritten to delay its output until the very end, so if a low memory condition occurs and needs to stop execution then no real output will show up before the skip marker.

Damien George	9274f80130	esp32/boards/ESP32_GENERIC_S3: Reinstate old FLASH_4M variant. ... Commit 6201e77999 removed the ESP32_GENERIC_S3 FLASH_4M variant from `board.json`. But the firmware still exists on the download server, and it makes sense to still keep those old versions available for download, just like all other older versions are still available. This commit introduce a new scheme for `board.json` whereby old variants that are no longer built can be moved to the "old_variants" section. This keeps them available on the download page, allowing a way to deprecate individual board variants without removing them entirely. An optional string can be added to the old variant to describe why it's obsolete and what to use instead. Signed-off-by: Damien George <damien@micropython.org>	2025-12-16 16:22:03 +11:00

Damien George	9939eae599	tests/serial_test.py: Add a serial echo test. ... The existing `serial_test.py` script tests data in/out throughput and reliability. But it only tests data sizes that are a power of two, which may not catch certain errors with USB transmission (because FS packet size is 64 bytes). This commit adds a new echo sub-test to the `serial_test.py` script. It sends out data to the target and gets the target to echo it back, and then compares the result (the echo'd data should be equal to the sent data). It does this for data packets between 1 and 520 (inclusive) bytes, which covers USB FS and HS packet sizes (64 and 512 respectively). It uses random data for the test, but seeded by a constant seed so that it's deterministic. If there's an error then it prints out all the sent and echo'd data to make it easier to see where it went wrong (eg if the previous packet was repeated).

On RP2350B where there are more than 32 pins, using `pio_sm_set_pins_with_mask()` and `pio_sm_set_pindirs_with_mask()` is not correct because their arguments are `uint32_t` and higher bits get lost when `pio.gpio_base(16)` is used.
