Hello. I'm new here. I was in need of support for indirect flashing of a flash part that is not supported by #vivado. I am working on adding support for the #Winbond W25Q256PW and #Xilinx XCAU7P-1SBVC484E, and have a working prototype. I will push it to my fork. Would this be a contribution others are interested in?

I also produced a PR:
https://github.com/trabucayre/openFPGALoader/pull/680

#FOSS tools are great. I couldn't have added this support to #vivado without a binary patch.

Xcau7p support by poleguy · Pull Request #680 · trabucayre/openFPGALoader

This has been tested on hardware. Adding support for two SPI Flash chips not supported by vivado for indirect programming. Added support for xcau7p-sbvc484 (using vivado 2025.2). Improved a couple ...

The AI memory super-cycle has a shadow story.
While headlines track HBM allocation and DDR5 contract resets, 2D NAND prices just spiked 2–3× in the corner of the market that powers automotive ECUs, factory PLCs, network switches, and medical devices.
What happened: Samsung announced MLC NAND end-of-life with final shipments in June 2026. Micron, SK hynix, and Kioxia capped legacy output. TrendForce projects worldwide MLC capacity dropping ~42% YoY in 2026.
What's filling the vacuum: Macronix Q1 2026 revenue +71% YoY, gross margin 40.8%, NAND revenue +382% YoY. Macronix moved customers from quarterly to monthly pricing. Winbond approved a record NT$42.1B 2026 capex and says capacity is booked through 2027.
Why it matters beyond embedded: legacy hardware residual values are inverting. Decommissioned switches, storage controllers, automation gear, and test instruments built ~2014–2022 are shifting from "candidate for shred" to "candidate for harvest and resale."

It's TEDIOUS to reverse engineer a proprietary NAND ECC algorithm.

So let's have an LLM do it for us!

Here's Winbond's NAND ECC algorithm (at least for W25N01GV)

Winbond NAND ECC algorithm

Reverse engineering proprietary algorithms can be _such_ a chore. So why not outsource that tedious work to the machines? Here's how "I" reverse engineered an ECC algorithm for Winbond NANDs.
