I am totally new to this community and just wanted to say thanks in advance for any help.
I recently bought a seeed xiao rp2040 and I am trying to install the json file in the Arduino ide board manager. Every time I try to install the file I get a crc doesn’t match error. I have read everything I think that I could to resolve this problem but I just cant figure it out. Maybe someone can give me some advice.
You are not doing anything wrong. The server is borked for the latest version, 2.7.2, and has been for some time.
Just tell the Board Manager to install version 1.12.0
It works for me.

Dave
Footnote: I think that the hardest job in the world is in IT for servers like this. No one appreciates you, personally, when things work out OK, and every one absolutely hates you, personally, when things go wrong. Sometimes they even accuse of not testing this stuff when you put up new versions.
Thanks for taking your time out to help me. At least I know it is nothing I am doing wrong. I installed version 1.12.0 and that loaded fine. I don’t see the new version yet, but I will keep an eye out for it.
That was a mistake when I said that there is a later version. I removed that paragraph from my post.
Sorry if it confused you.
Happy coding!
Regards,
Dave
No problem thanks again
I confirm: 2.7.2 fails but 1.12.0 works.
Could Seeed fix that issue, please?
We have uploaded the correct onboard file to the server, but it still reports CRC checksum error when downloading from Arduino. Both R&D and Cloud Center are working hard to identify the problem, please wait. At this time, it is recommended to use a version lower than version 2.7.2 to download and use, thank you.
Up to release 1.12.0, the RP2040 board package was based on the excellent work by Earle F. Philhower built on top of the official Raspberry Pi SDK.
Does the new version 2.7.2 rely on the arduino-pico board package?
As I wrote on my website,
However, I’ve faced two issues with release 2.1.0:
- Large projects fail to upload and/or run, while they succeed with the arduino-pico board package. The issue was reported at RPI Pico: LED blinks 4 long, 4 short, then again #3#6.
- The Segger J-Link programmer-debugger experiences issues with the underlying mbedOS when debugging against the Pico.
So the 2.7.2 version would be a very severe regression over the 1.12.0 version.
I am also still having this issue as of now
Version 2.7.2 only fixes the compatibility problem between XIAO RP2040 and XIAO expansion board, it is still in testing stage, we suggest you use version 1.12.0 first.
I’m brand new to the Xiao, Pi, Aurduino IDE environment. Very confused about how to get started. I’d like to make some projects using the RP2040 board but so far I have not found the board files from seeed that support it. This is stopping me from purchasing these boards. I did read the getting started blog which explained about the board files to download and I have done that and installed it into the board manager in the arduino IDE but I still can not find support for the RP2040.
Any pointers on how to get the board supported?
Thanks Mike
The rp2040 c SDK in vscode is actually my favorite way to work, using a simple Power shell script to build, reset and Flash the RP2040/2350. There’s a ton of stuff out there for it that will run great on the Xiao modules.
But there’s also an extension that helps
Thanks. I’ll see if I can get that to work. Brand new at this so just trying to figure out how to get started
Cheers Mike
Hi there,
So in the Arduino IDE, you need to add it, check it out…
The Wiki link is key copy it to get started. here are five PIC’s on what and how to:
LMK if you get stuck, but it is pretty straight forward once over the hump.
You will need to restart the IDE after you load the examples, it will prompt you.
Step one open preferences and paste in the GIT link to the New board files
paste it in there, and hit OK, it will do it’s thing…
after it finishes , you can locate it in the “Select other board and port…”
it might be gray but select it anyway , after it will do it’s thing and be normal, then you can Find it listed in the examples and pick any to try.
It may ask for a restart, YMMV 
should be good to go at this point., Let us know.
