@jakobsen_jan Have you tried using my project and running `i2cdetect` command?

@janmarjanovic I got this board, Quartus = OK, JTAG = OK. LED cnt = OK. PCIe Riser card with 12V PSU, Uart via a FTDI USB to 3V3 with TX to PCIe pin A11 (FPGA AB28) data goes fine to the FPGA = OK TX back on PCI B5, B6 AW26, AV26 tried pullup. (floating on scope) = NEG Any advise? Thx

Please welcome a new addition to my collection of cheap #FPGA boards from eBay. This one is a PCIe variant of Pikes Peak accelerator from Microsoft. (1/8)

Nuclear spins of Yb-171 exploited to manipulate qubits before they are read out - potentially leading to efficient error-correction schemes for trapped-atom computing platforms. Read go.aps.org/3ukRFic & go.aps.org/3SWJOBJ @atom_computing @JILAscience #PRXqst

1,180 qubits and counting! Today, we became the first company developing universal, gate-based #quantum computers to exceed the 1,000-qubit threshold.  Learn more about this accomplishment and our quest to build a fault-tolerant #quantumcomputer. atom-computing.com/quantum-startu…

@RuurdKeizer Yup, the USB chip that implements JTAG needs to be initialized: #initialization" target="_blank" rel="nofollow noopener">github.com/j-marjanovic/j…

@janmarjanovic Is there something special you did to make the flash programmer recognize the flash chip? If I add the ECPQ device and start read/write I just get an error. It's not recognized on the JTAG chain.

Close your eyes, take a deep breath and think about all the packages on can install with Expanded Security Maintenance for Applications. #Ubuntu

Happy #NationalPeriodicTable Day! Here at Atom, we are partial to alkaline earth metals (group two on the periodic table). Learn why we use atoms from alkaline earth metals as qubits in our atomic array #quantumcomputing hardware technology. #quantum bit.ly/3RHIekL

Electronic noise is a big problem in micro electronics. A DESY team now managed to measure so-called phase noise with 500 times greater precision than has been possible before. This could significantly improve how electronic components are tested: desy.de/news/news_sear…

@vsidou There is a workaround needed to unlock the second PCIe core, otherwise it works fine with a normal Quartus.

@janmarjanovic Thanks. I've got one PCIe model. I will read all the blogpost and try. Seems i need Quartus standard version. Does Quartus need a specific license for the PCIe card ?

@vsidou Somehow yes. I have managed to get all the parts running (PCIe, DDR3, QSFP, …) - see my blog series for details, but recently got distracted from my hobby FPGA projects by my new job.

@janmarjanovic @GuruMeditation6 @jcarolinares Did you manage in the end to use the PCIe model as a general purpose FPGA board by any chances ?

With the power of the IPMI (and @picmg_org extensions) and with the ymodem in u-boot, I have managed to bootstrap myself into a Zynq board more than 8000 km away.

@whitequark A good excuse to buy some measurement equipment: rohde-schwarz.com/us/products/ae…

i have definitively excluded the microwave and the light fixture from the list of possible causes, and i'm reasonably sure it is not the fridge compressor either the only other appliance running nearby is an aircon, but it's an inverter model so it doesn't cycle...

the WiFi card firmware in this laptop consistently crashes when i go to the kitchen. could transfer tens of gigabytes fine two meters and one inner wall away from the kitchen table. move it there and a few minutes later:

I imagine that it might be a useful feature in some cases, but sending 4 broadcast packets every 15 seconds sounds quite excessive. Anyway, developing the UDP/IPv4 core in the FPGA became much pleasant when I shut down the TCF agent.

@hansfbaier Gennum GN4124 is another device with similar functionality, I have seen it used quite often in some older electronics for particle accelerators.

Today I discovered that really exciting PCIe-Interface chip by @WCH_TECH wch-ic.com/products/CH368…

@wing_chester @dsp8bit Yes, it requires the Standard Edition, Stratix V is not supported in the Lite Edition.

@janmarjanovic @dsp8bit Wait but don't you need a standard license to use it?
