I Designed My Own RP2350 Board and You Can Too!

Great work! Looking forward to the next videos.

Thanks! Since I am still waiting for RP2350 availability I am working on video edit for VGA and FPGA extension.

[@ЕвгенийШепард-р2х]

Good work! Thank you for your video!

[@matgla95]

Thanks!

[@LoganE01]

Very cool stuff. I hope to study enough to make my own board one day.

[@matgla95]

Thanks! I hope it'll be working fine after soldering :D

Now this is an interesting project. Exited to see it comming to live. A risc5 and arm cpu in 1? 😮

[@matgla95]

Yes, exactly! Raspberry Pico 2 is already available to purchase. RP2350 inside contains dual core arm cortex-m33 and dual core risc-v, but you have to select which one you are going to use at startup ( as far as I know )

[@DenisBodor]

It's "risk 5" not "risk vee" ;)

[@matgla95]

Of course you're right! I didn't know that, so thanks! So I'm sorry about my mistake inside video.

Is the external PSRAM or QSPI ram able to be encrypted on the fly or at rest with a key stored using the internal OTP storage? Like is this actually a secure device that will prevent people from hacking your IoT application and dumping your secrets

[@matgla95]

That's rather question for RP2350 datasheet or designers (through raspberry forum), but looking quickly inside documents I don't think so. RP2350 contains encryption module with secure boot, but the flow is to verify image from QSPI flash then load decrypted image inside SRAM. And I would need to deep dive into datasheet, but I believe there is a way to prevent external access through JTAG/SWD and your software should be quite safe (of course except security leaks inside firmware itself)

Interesting video, but I'm afraid I still don't really know how to design a PCB, I thought maybe you would go into detail about the design process but this was more of an overview of what you did.

[@matgla95]

Yes, that's just overview. I just wanted to cover transition towards RP2350 from my RP2040 board, short overview of design and hopefully in near future short overview of soldering and debugging. Actually design for RP2040 or RP2350 is really well described inside their official hardware design guides. Second thing needed is general knowledge about PCB design and there is a lot of high quality channels with with people much wiser in that domain than me. I personally was learning from Robert Feranec channel.

where can I buy the RP2350 chip?

[@matgla95]

Standalone chips are not yet available. But you can buy Raspberry Pico 2 which contains RP2350A.
