 If you have built a Raspberry Pi Picoprobe, you can use OpenOCD to handle your sketch uploads and for debugging with GDB.

 Under Windows a local admin user should be able to access the Picoprobe port automatically, but under Linux `udev` must be told about the device and to allow normal users access.
@@ -240,28 +244,8 @@ If for some reason the device file does not appear, manually unplug and re-plug

 Once Picoprobe permissions are set up properly, then select the board "Raspberry Pi Pico (Picoprobe)" in the Tools menu and upload as normal.

-# Uploading Sketches with pico-debug
-[pico-debug](https://github.com/majbthrd/pico-debug/) differs from Picoprobe in that pico-debug is a virtual debug pod that runs side-by-side on the same RP2040 that you run your code on; so, you only need one RP2040 board instead of two.  pico-debug also differs from Picoprobe in that pico-debug is standards-based; it uses the CMSIS-DAP protocol, which means even software not specially written for the Raspberry Pi Pico can support it.  pico-debug uses OpenOCD to handle your sketch uploads, and debugging can be accomplished with CMSIS-DAP capable debuggers including GDB.
-
-Under Windows and macOS, any user should be able to access pico-debug automatically, but under Linux `udev` must be told about the device and to allow normal users access.
-
-To set up group-level access to all CMSIS-DAP adapters on Ubuntu (and other OSes which use `udev`):
-````
-echo 'ATTRS{product}=="*CMSIS-DAP*", MODE="664", GROUP="plugdev"' | sudo tee -a /etc/udev/rules.d/98-CMSIS-DAP.rules
-sudo udevadm control --reload
-sudo udevadm trigger -w -s usb
-````
-
-The first line creates a device file in `/dev` that matches all CMSIS-DAP adapters, and it enables read+write permissions for members of the `plugdev` group. The second line causes `udev` to load this new rule. The third line requests the kernel generate "device change" events that will cause our new `udev` rule to run. 
-
-If for some reason the device file does not appear, manually unplug and re-plug the USB connection and check again. The output from `dmesg` can reveal useful diagnostics if the device file remains absent.
-
-Once CMSIS-DAP permissions are set up properly, then select the board "Raspberry Pi Pico (pico-debug)" in the Tools menu.
-
-When first connecting the USB port to your PC, you must copy [pico-debug-gimmecache.uf2](https://github.com/majbthrd/pico-debug/releases/) to the Pi Pico to load pico-debug into RAM; after this, upload as normal.

+RP2350 Specific Notes
+=====================
+
+The RP2350 chip (present on the Raspberry Pi Pico 2 board and many others)
+is supported by the core with some minor caveats:
+
+* PSRAM is supported via a new ``pmalloc`` call and ``PSRAM`` variable decorator.
+* Both RP2350A and RP2350B (48 GPIOs) are supported.
+
+ARM and RISC-V Modes
+~~~~~~~~~~~~~~~~~~~~
+
+Either set of cores can be used on the RP2350, ARM Cortex-M33 or RISC-V Hazard3.
+Select the desired core from the IDE menus under ``Tools->CPU Architecture``.
+As of the initial release, all libraries should work under the new RISC-V mode with
+the exception of FreeRTOS.  If not, patches are always welcome.
+
+P2350-E9 Errata ("Increased leakage current on Bank 0 GPIO when pad input is enabled")
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Like all chips, the RP2350-A2 stepping has post-silicon chip errata covering certain
+bugs found after the chip was manufactured.  Probably the most (in)famous and concerning
+is RP2350-E9 which is noted as resulting in "Increased leakage current on Bank 0 GPIO
+when pad input is enabled."  At a high level, this means that in some cases when an
+input pin is being driven by a weak (high impedance) input, it may not read properly.
+
+After discussion with the community and exploration of the issue by many users, this
+core has decided not to implement any forced workarounds for this issue.  Given the
+physical nature of the problem and how no one specific solution is appropriate for
+all conditions.
+
+For more information please read the errata yourself and check the Raspberry Pi Forums
+for the latest updates.

Earle F. Philhower, III	599c226b8c	Workaround PSRAM cache invalid'n by reading flash (#2551 ) * Workaround PSRAM cache invalid'n by reading flash Fixes #2537 While waiting for a working direct cache flush routine, try and force the cache to evict all PSRAM values by reading a bunch of flash addresses (which share the XIP cache). This hurts performance when PSRAM is not used, but is required for correctness until we have a working XIP flush. * Invalidate after cleaning the cache line gmx from the RPI forums came up with this hack and it seems to work! https://forums.raspberrypi.com/viewtopic.php?p=2262371#p2262371	2024-10-23 16:12:37 -07:00

Earle F. Philhower, III	fdd7557156	Preserve PSRAM QMI interface around flash ops (#2539 ) The flash ROM routines seem to overwrite the QMI configuration we set for PSRAM, rendering it unreadable after any erase or write or ID command. Wrap the 4 flash control functions to preserve the QMI state on the RP2350. On the RP2040, simply pass through the call. Fixes #2537	2024-10-12 12:32:56 -07:00

Earle F. Philhower, III	b2ec6ecb09	GCC to 12.4, Newlib to 4.3.0, faster RP2350 libs (#2480 ) Newlib built using `-Os` causes things like `memcpy` to be very slow on the RP2350 because it uses byte-wise operations. On the RP2040 this doesn't matter because there is a ROM routine we use instead of the library, but on the Pico 2 it's almost 10x slower than the optimal method. Update GCC to 12.4 Update Newlib to 4.4.0 Move to -O2 library compilation New toolchain looks to add ~10K to RP2350 flash usage (less on the RP2040).	2024-09-19 17:03:23 -07:00
