Damien George	a9384c71c5	extmod/extmod.mk: Switch from drivers/cyw43/cywbt to lib/cyw43-drivers. ... The cyw43-driver now provides the Bluetooth initialisation code, making `drivers/cyw43/cywbt.c` obsolete. To use the new code a port must enable the `CYW43_ENABLE_BLUETOOTH_OVER_UART` option. Some ports have yet to migrate to the new code, so in the meantime they can explicitly add the old source to their source list and continue to use it without change.

Phil Howard	b7d5caf2a3	rp2/mpconfigport: Configure heap for PSRAM. ... PSRAM will be used exclusively if MICROPY_GC_SPLIT_HEAP == 0, it will be added to RAM if MICROPY_GC_SPLIT_HEAP == 1, and the system will fall back to RAM only if it's not detected. Due to the size of PSRAM, GC stack was overflowing and causing the GC to scan through the entire memory pool. This caused noticable slowdowns during GC. Increase the stack from 256 to 4096 bytes to avoid overflow and increase the stack entry type size to accomodate 8MB+ PSRAM. Changes are: - ports/rp2/mpconfigport.h: Make split-heap optional and enable by default. - ports/rp2/mpconfigport.h: Increase GC stack entry type to uint32_t. - ports/rp2/mpconfigport.h: Raise GC stack size.

Introduce two new port/board defines: - MICROPY_HW_ENABLE_PSRAM to enable PSRAM. - MICROPY_HW_PSRAM_CS_PIN to define the chip-select pin (required).

iabdalkader	9e9be83fd6	tools/mpremote: Allow .img for ROMFS file and validate ROMFS image. ... Currently the tool allows writing an invalid ROMFS image, with a bad header or images smaller than minimum size, and only checks the image extension. This commit allows deploying a ROMFS with either a ".img" or ".romfs" extension (in the future support may be added for other extensions that have different semantics, eg a manifest), and validates the image header before writing.

Installing it manually using the "master" branch means the latest released version is used (instead of a possibly unstable development version), and also makes building each rp2 board a little faster.

Alessandro Gatti	fda9bf4917	esp32/esp32_common.cmake: Clean up RISC-V directives. ... This commit cleans up a couple of RISC-V specific directives in the build script. Namely, removes the forced inclusion of the "riscv" component and introduces proper mpy-cross flags. The "riscv" component is already included by the ESP-IDF build framework, as certain low-level components would not build otherwise, so there is no need to add it to the required components list. The architecture flag for mpy-cross is now set for RISC-V targets, as it was previously set only for Xtensa targets (and it relied on a string comparison rather than using the appropriate configuration variable).

Damien George	1660faacf6	stm32/boards/PYBD_SF2: Restart qspi memory-mapped mode during startup. ... The PYBD boards use an F7xx which has an errata 2.4.3: Memory-mapped read operations may fail when timeout counter is enabled This is unfortunate because it means that once QSPI memory-mapped flash is accessed the QSPI peripheral will leave the CS pin active (low) forever, which increases power consumption of the SPI flash chip (because it's active and waiting for commands). The exact amount of power increase depends on the flash, but the PYBD_SFx increase by about 2.5mA. Previously this increase in power only happened when QSPI flash was needed, eg on PYBD_SF2 when mbedtls or nimble libraries were used. On PYBD_SF6 it's actually never used. But with the introduction of ROMFS which lives in the QSPI flash, the memory is always access on start up to see if the ROMFS contains a valid image (it must read the memory to find out). That means these boards always consume about 2.5mA more after starting up (compared to when ROMFS is disabled). The fix in this commit is to explicitly restart the QSPI memory mapped mode during the start up process. More precisely, the restart is done after querying the ROMFS and just before trying to execute `boot.py`. That's the right location to keep power consumption permanently down if the QSPI is never used (eg ROMFS image doesn't exist).

Andrew Leech	b33b9f8121	stm32/main: Catch and report corrupted lfs filesystem at startup. ... On stm32, the startup code attempts to mount the configured filesystem. If there is an existing littlefs filesystem that's suitable corrupted it's possible for the reported blocksize to be incorrect here: uint32_t block_size = lfs2_fromle32(superblock->block_size); This `block_size` (which is read from the filesystem iteself) is used to create the len argument passed to `pyb_flash_make_new()`. In that function the len arg is validated to be a mutliple of the underlying hardware block size, as well as not bigger than the physical flash. Any failure is raised as a ValueError. This exception is not caught currently in main, it flows up to the high level assert / startup failure. As this occurs before `boot.py` is run, the users (potentially frozen) application code doesn't have any opportunity to detect and handle the issue. This commit adds a helper function which attempts to create a block device, and on error returns `None` instead of raising an exception. Using this in main means that a potentially corrupt filesystem will simply remain unmounted, and the application can handle the issue safely. The fix here also handles the case where the littlefs filesystem is valid but the autodetection code (which detects the filesystem size) does not work correctly. In that case it will retry mounting the filesystem using the whole size of the block device. Signed-off-by: Andrew Leech <andrew.leech@planetinnovation.com.au>	2025-04-03 15:08:58 +11:00
Mark Seminatore	f96417dbf2	rp2/cyw43_configport: Fix cyw43 mDNS by properly starting mDNS on netif. ... The rp2 port has an incomplete mDNS implementation. The code in `main.c` calls `mdns_resp_init()` which opens the UDP socket for mDNS. However, no code in the cyw43 driver makes the proper calls to `mdns_resp_add_netif()` and `mdns_resp_remove_netif()` to send the announce packets. The wiznet5k driver does make these calls and was used as a model for these changes. This commit attempts to address this by very small changes to the `ports/rp2/cyw43_configport.h` file. The change uses new cyw43 driver hooks to map the driver macros `CYW43_CB_TCPIP_INIT_EXTRA` and `CYW43_CB_TCPIP_DEINIT_EXTRA` to the appropriate lwIP mDNS calls. Fixes issue #15297.

Rather than having Make calling CMake to generate a list of submodules and then run a Make target (which is complex and prone to masking other errors), implement the submodule update logic in CMake itself. Internal CMake-side changes are that GIT_SUBMODULES is now a CMake list, and the trigger variable name is changed from ECHO_SUBMODULES to UPDATE_SUBMODULES.

Angus Gratton	6fa498cba1	rp2/mpnetworkport: Fix lost CYW43 WiFi events when using both cores. ... There's a very odd but predictable sequence of events that breaks Wi-Fi when using both cores: 1) CPU1 calls pendsv_suspend() - for example sleep() causes a softtimer node to be inserted, which calls pendsv_suspend(). 2) CYW43 sends wakeup IRQ. CPU0 GPIO IRQ handler schedules PendSV and disables the GPIO IRQ on CPU0, to re-enable after cyw43_poll() runs and completes. 3) CPU0 PendSV_Handler runs, sees pendsv is suspended, exits. 4) CPU1 calls pendsv_resume() and pendsv_resume() sees PendSV is pending and triggers it on CPU1. 5) CPU1 runs PendSV_Handler, runs cyw43_poll(), and at the end it re-enables the IRQ *but now on CPU1*. However CPU1 has GPIO IRQs disabled, so the CYW43 interrupt never runs again... The fix in this commit is to always enable/disable the interrupt on CPU0. This isn't supported by the pico-sdk, but it is supported by the hardware. Fixes issue #16779. This work was funded through GitHub Sponsors.
