Leave that to the main app instead, so we don't reset peripherals twice.
* ota: fix copy error for riscv headers
* ota: initialize bootrom bit ops and add explanation
* Adds RISC-V compilation option to the IDE and Platform.IO.
* Build RP2350-RISCV libpico, libbearssl
* Fix RP2350 BearSSL library (was copied from RP2040, now built for M33)
* New GCC 14.2 toolchain is required (12.4 RISC-V support is borked)
* Newlib locking fixed prototypes
* Manually force all runtime init code into RP2350 binaries
* Add RISC-V to CI
* Remove RP2350 BOOT2.S files, binaries (not used)
* Clean up minor GCC 14.x warnings
* Add RP2350-RISCV OTA build, link
* Add RISC-V FreeRTOS files (configuration still not running, but builds)
* Add basic documentation
The uninitted RAM macro would fail because the OTA code would clear out the
first 50KB or so of RAM to copy its code and global values.
Move all global values to the end of RAM in OTA, and then align any uninitted
vars to a 16KB unit to ensure it won't appear in the 1st part of RAM that is
still needed to copy the OTA executable.
In the normal case, without any uninit_ram vars, no additional space is used.
When uninit_ram is used, up to 16KB of space may be lost to get that alignment,
but it will work properly.
Fixes#1188
Adds a 12K OTA stub 3rd stage bootloader, which reads new firmware
from the LittleFS filesystem and flashes on reboot.
By storing the OTA commands in a file in flash, it is possible to
recover from a power failure during OTA programming. On power
resume, the OTA block will simply re-program from the beginning.
Support cryptographic signed OTA updates, if desired. Includes
host-side signing logic via openssl.
Add PicoOTA library which encapsulates the file format for
the updater, including CRC32 checking.
Add LEAmDNS support to allow Arduino IDE discovery
Add ArduinoOTA class for IDE uploads
Add MD5Builder class
Add Updater class which supports writing and validating
cryptographically signed binaries from any source (http,
Ethernet, WiFi, Serial, etc.)
Add documentation and readmes.
