Assessing project data needs.

Running design review.

Analyzing the schematic.

I checked it.
  • There is no ERC result currently available for the decoupling_caps review category, so Flux is not reporting a missing-decoupling warning around X1 right now. The decoupling check is the correct ERC category for this kind of issue
  • In the schematic, X1 has:
    • VDD tied to VCC_3V3
    • GND tied to GND
    • OUT connected only to IC1 CLKI
  • The VCC_3V3 net also includes C17 and C18, so there is capacitance on the rail, but it is not obvious from ERC alone that one of those is a dedicated local bypass capacitor specifically for X1.
So the answer is:
  • ERC: no missing-decoupling flag reported for X1
  • Design clarity: still worth checking whether C17 or C18 is intended to be the oscillator’s local decoupler
If you want, I can next check the oscillator datasheet guidance and tell you whether X1 should have its own dedicated 100 nF cap placed right at the supply pin.

Navigating project saving options.

Checking if I can make the changes for you.

Reading docs about How do projects save in Flux? Does Flux automatically save project changes or is there a manual save action?.

Reading docs about Manual save project in Flux editor autosave project changes save button.

Reading docs about Project autosave change history save changes automatically Flux project version control save.

I can’t save the project for you from chat.
I could not find relevant Flux documentation for a manual project-save feature, so this probably means that action isn’t available here.

Prototype / evaluation hardware only

Primary host interface is USB through the on-board USB-to-UART bridge and USB-C connector. SWD header is retained only for programming and bring-up. Mining subsystem uses dedicated 25MHz oscillator X1 into BM1397 CLKI.

12V input main power path with USB used for control and monitoring interface support

Prototype

USB is the primary control and monitoring interface, SWD is secondary debug only, and the mining core receives a stable dedicated 25MHz reference clock from X1.
