The RP2350 is Raspberry Pi’s second-generation in-house microcontroller design. The Raspberry Pi RP2350 is a major upgrade over the earlier Raspberry Pi RP2040, boasting newer Arm Cortex-M33 cores running at a faster 150MHz, almost twice the static RAM (SRAM) plus support for external pseudo-static RAM (PSRAM), an additional programmable input/output (PIO) block, and more — but it also brings with it an architectural complexity: the presence of two RISC-V cores, based on the free and open source Hazard3 design, which can be chosen in place of the Arm cores or even split with one Arm and one RISC-V core running simultaneously.

New microcontroller boasts a choice of 150MHz Arm Cortex-M33 or RISC-V Hazard3 cores, a dedicated display peripheral, 520kB SRAM, and more. RP2350 is built using quad-core dual-architecture with two ARM and two RISC-V cores, but only two of those four cores can run at the same time. There is 520 Kb of SRAM memory on the chip and the new features include Arm TrustZone, 8 Kb OTP memory and Secure Boot support. The previous PR2040 had two Arm Cortex-M0+ cores with a maximum clock frequency of 133 MHz and 264 KB of SRAM memory. It is possible to integrate extra two megabytes of Flash to the same chip package.

“Raspberry Pi Pico 2 is our new $5 microcontroller board, built on RP2350: our new high-performance, secure microcontroller,” the company says of its latest launch. “With a higher core clock speed, double the on-chip SRAM, double the on-board flash memory, more powerful Arm cores, optional RISC-V cores, new security features, and upgraded interfacing capabilities, Raspberry Pi Pico 2 delivers a significant performance and feature boost, while retaining hardware and software compatibility with earlier members of the Raspberry Pi Pico series.”

For programming Raspberry Pi RP2350′shave Day-One Rust Support. Pallant says, “this is the first ever microcontroller launch with Rust support out-of-the-box.” Raspberry Pi Pico 2 board serves as a quick-start development platform.

    A closer look at Raspberry Pi RP2350’s HSTX high-speed serial transmit interface
    The Raspberry Pi RP2350 microcontroller adds an HSTX (High-Speed Serial Transmit) interface adding the PIOs (Programmable IOs) introduced on the Raspberry Pi RP2040 three years ago. The RP2350 MCU now has three PIOs and one HSTX interface going over 8x GPIOs. So let’s try to better understand what HSTX is exactly, what it is used for, and how it differs from PIOs. We’ll also check out some programming examples in C and MicroPython.

    The high-speed serial transmit (HSTX) interface is detailed in the RP2350 datasheet starting on page 1118 where it reads “The high-speed serial transmit (HSTX) interface streams data from the system clock domain to up to 8 GPIOs at a rate independent of the system clock”. Reading further, we also learn that it runs at 150 MHz enabling up to 300 Mbps per pin with DDR output operation, or a combined 2,400 Mbps over 8 pins if I understood that right…

    The new Raspberry Pi Pico 2 with its RP2350 microcontroller has only been with us for a short time, and thus its capabilities are still being tested. One of the new peripherals is HSTX, for which the description “High speed serial port” does not adequately describe how far it is from the humble UART which the name might suggest. CNX Software have taken a look at its capabilities, and it’s worth a read.

    With a 150 MHz clock and 8 available pins, it’s a serial output with a combined bandwidth of 2400 Mbps, which immediately leaves all manner of potential for streamed outputs. On the RP2040 for example a DVI output was made using the PIO peripherals, while here the example code shows how to use these pins instead. We’re guessing it will be exploited for all manner of pseudo-analogue awesomeness in the manner we’re used to with the I2S peripherals on the EP32. Of course, there’s no corresponding input, but that still leaves plenty of potential.

    https://www.cnx-software.com/2024/08/15/raspberry-pi-rp2350-hstx-high-speed-serial-transmit-interface/

The RP2350 MCU now has three PIOs and one HSTX interface going over 8x GPIOs. So let’s try to better understand what HSTX is exactly, what it is used for, and how it differs from PIOs.

Reading further, we also learn that it runs at 150 MHz enabling up to 300 Mbps per pin with DDR output operation, or a combined 2,400 Mbps over 8 pins if I understood that right…

    Here’s a bit more of the description from the datasheet

    The HSTX is asynchronous from the rest of the system. A 32-bit-wide FIFO provides high-bandwidth access from the system DMA. The command expander performs simple manipulation of the datastream, and the output shift register portions the 32-bit data out over successive HSTX clock cycles, swizzled by the bit crossbar. The outputs are double-data-rate: up to two bits per pin per clock cycle.

    HSTX drives data through GPIOs using DDR output registers to transfer up to two bits per clock cycle per pin. The HSTX balances all delays to GPIO outputs within 300 picoseconds, minimizing common-mode components when using neighboring GPIOs as a pseudo-differential driver. This also helps maintain destination setup and hold time when a clock is driven alongside the output data.

    The maximum frequency for the HSTX clock is 150MHz, the same as the system clock. With DDR output operation, this is a maximum data rate of 300Mb/s per pin. There are no limits on the frequency ratio of the system and HSTX clocks, however, each clock must be individually fast enough to maintain your required throughput. Very low system clock frequencies coupled with very high HSTX frequencies may encounter system DMA bandwidth limitations since the DMA is capped at one HSTX FIFO write per system clock cycle.

    On the Raspberry Pi RP2350, GPIOs 12 through 19 are HSTX-capable. Note that HSTX is output-only, so it’s not quite as flexible as PIOs which allow users to create all sorts of high-speed (or not) interfaces.

    What HSTX can it be used for?

    HSTX is capable of high-speed transfer but can only transmit data and not receive it, so it appears especially useful for video outputs and display interfaces. However, it would not be suitable for bidirectional transfers, for instance, you could not emulate an Ethernet interface.

    The Raspberry Pi RP2040’s PIOs were used to create DVI, VGA, and composite video outputs, but in the RP2350 board the programmable I/O blocks may be freed, and the HSTX interface used instead. While you could use the Raspberry Pi Pico 2 to play around with the HSTX interface, you’d have some soldering to do, and a more convenient way to be started is getting a board like the RP2xxx Stamp Carrier XL in combination with the R2350 Stamp module since it exposes the HSTX interface through a micro HDMI port.

    Raspberry Pi provides two HSTX code samples in the Raspberry Pi Pico C/C++ SDK:

    dvi_out_hstx_encoder – This sample generates DVI output using the command expander and TMDS encoder in HSTX. The frame buffer resolution is set to 640×480. This example requires an external digital video connector connected to GPIOs 12 through 19 with appropriate current-limiting resistors, e.g. 270 ohms. This example can be used directly with the Pico DVI Sock board which can be soldered onto a Raspberry Pi Pico 2.
    spi_lcd – This sample drives an ST7789 SPI LCD using the HSTX. The SPI clock rate is fully independent of (and can be faster than) the system clock. It was tested at a 240×240 resolution using a WaveShare 1.3-inch ST7789 module.

    There’s currently a significant amount of confusion around the full extent of the GPIO hardware issue in the Raspberry Pi RP2350 microcontroller, with [Ian] over at [Dangerous Prototypes] of Bus Pirate fame mentioning that deliveries of the RP2350-based Bus Pirate 5XL and 6 have been put on hold while the issue is further being investigated. Recorded in the MCU’s datasheet as erratum RP2350-E9, it was originally reported as only being related to the use of internal pull-downs, but [Ian] has since demonstrated in the primary issue ticket on GitHub that the same soft latching behavior on GPIO pins occurs also without pull-downs enabled.

    RISC-V on Raspberry Pi Pico 2
    https://www.raspberrypi.com/news/risc-v-on-raspberry-pi-pico-2/

    The Hazard 3 RISC-V cores on the RP2350 were designed by Raspberry Pi’s own Luke Wren in his spare time – and as they’re open source, you can download the design files yourself and start poking around in the very same chip that will eventually be in use on millions of units out in the wild. As Eben Upton puts it: “In adding Hazard3 to RP2350, we’re aiming to give software developers a chance to experiment with the RISC-V architecture in a stable, well-supported environment, and to popularise Hazard3 as a clean, open core, suitable for verbatim use in other devices, or as a basis for further development.” Luke’s reflections first appeared in issue 145 of The MagPi.

    I am excited about RISC-V because it lets you perform your mad-scientist architecture experiments on top of a clean and standard architecture. If you look at something like CHERI, which is a super-exciting development in the embedded security space, those folks have just gone and written a spec, and you can just go and implement it — no need to wait for it to be served on a plate.

    Pico Logic Analyzer Gets New Version
    https://hackaday.com/2024/12/12/pico-logic-analyzer-gets-new-version/

    [Happy Little Diodes] built a Pi Pico logic analyzer designed by [El Dr. Gusman] using the original design. But he recently had a chance to test the newest version of the design, which is a big upgrade. You can see his take on the new design in the video below.

    The original design could sample 24 channels at 100 MHz and required two different PCBs. The new version uses a single board and can operate up to 400 MHz. There’s also a provision for chaining multiple boards together to get more channels.

    You can set the level shifters to use 5V, 3.3V, or an external voltage. Since [Happy] is working on a ZX Spectrum, the 5V conversion is a necessity.
