Baochip @baochip.com · 01/06/2026Sorry for the re-post, Bluesky posted the image with the transparency layer mapped to black, making all text unreadable. 050
Baochip @baochip.com · 01/06/2026The Baochip-1x is IR-inspectable. But, how does one read chips, and what does it even mean? Here's a blog post put out by @bunnie.org that helps make sense of the Baochip-1x SRAM macros, and its implications for trusted boot: www.bunniestudios.com/blog/2026/on... 2164

Baochip @baochip.com · 20/03/2026One of my favorite features about the Baochip-1x is the BIO. I've just put out a post explaining the origin of the BIO, including a comparative study against the PIO and some examples of how to use it. www.crowdsupply.com/baochip/daba... 0183

Baochip @baochip.com · 08/03/2026Two of them run by one operator can do about that volume in a week. 020
Baochip @baochip.com · 07/03/2026Production tester for the dabao is ready! 100% of boards run through a test where every I/O is toggled, both buttons are pressed, serial ports tickled, and an initial OS image is loaded. Voltages and currents are also checked. The test checks for errors in soldering, and/or faulty components. 3392
Baochip @baochip.com · 07/03/2026Yah, it's a crossbar that lets each of the 4 CPUs talk to 4 FIFOs for inter-CPU communication. 000
Baochip @baochip.com · 07/03/2026Just a pair of anti-stat plastic tweezers does the trick. The socket is precision milled to the shape of the chip and the chip dimensional tolerance is very tight, so it just snaps right in. 010
Baochip @baochip.com · 03/03/2026😬 I keep asking people if I should be taking off a tinfoil hat, and someone offered me a lead hat instead. 010
Baochip @baochip.com · 02/03/2026Note that this initial campaign is limited to 3,500 boards total. I don't think we're at risk of hitting that limit, but it's probably worth a mention just in case! 060
Baochip @baochip.com · 02/03/2026Interested in trying out a Baochip-1x? The 'dabao' evaluation board is now taking pre-orders on Crowd Supply: www.crowdsupply.com/baochip/dabaocrowdsupply.comDabao Evaluation Board for Baochip-1xA powerful new RISC-V microcontroller with mostly open RTL 34911
Baochip @baochip.com · 31/01/2026The 'package' is the silicon die with some solder bumps attached to it via a redistribution layer. So the chip itself is pretty brittle. However, the real challenge is that the solder bumps are spaced 0.4mm apart - so the spring loaded pogo pins are closer to whiskers than they are to pins. 030
Baochip @baochip.com · 31/01/2026The socket has seen heavy use for initial device bring up and chip probe test development. However, its high cost and fragility limits its use to just the earliest bring up phases. If you are a lucky dabao Alpha board owner, the chip on that board was tested and programmed in this very socket! 280
Baochip @baochip.com · 31/01/2026The socket mounts to the board with spring loaded contacts; the carrier board is also custom to the socket. You can see some of the chip test & measurement power supplies on the board near the socket. The socket itself is quite expensive, a couple thousand dollars and some weeks to manufacture. 190
Baochip @baochip.com · 31/01/2026Here's what a socket looks like for chip scale packages. Each one is custom made for a given chip package. A couple samples of the 0.4mm pitch Baochip CSP devices are laid out on the lower rim of the socket for size reference. 2333
Baochip @baochip.com · 24/01/2026About $2k for a socket, yes. And yes, the initial smoke tests are done in a socket but the socket is huge, expensive, and also opaque so you can't do (for example) laser fault injection attacks while still in the socket. 010
Baochip @baochip.com · 23/01/2026Behold the graveyard of Baochips! Security testing is hard, after the chips are locked the only recourse is to desolder and replace them when a test goes wrong or an attack sensor is tripped. On the upside, I'm getting really good at reworking CSPs. 1170

Baochip @baochip.com · 01/12/2025The first cut of the code missed a branch delay slot, and so the two paths were different by three cycles. Open source means you can simulate code running on your chip, and be sure you got it right! 040
Baochip @baochip.com · 01/12/2025It's nice to be able to simulate your constant-time code and prove to yourself that you got it right. Pictured is a simulation of AES chaffing, where fake and real data are computed in a random order. The timing of fake->real and real->fake has to be identical in order to mask power side channels. 140

Baochip @baochip.com · 17/11/2025Backside IR image of the chip! The Baochip-1x is packaged specifically to enable you to verify that you've got the correct chip, and not a fake or a substitute part (see bunnie.org/iris for how). The final chip will have part numbering that overlaps the memory array on the lower third of the chip. 080
