I haven't tried it so I don't know how well it works
- Neywiny 2y agoIt looks like a passive mechanical adapter. I'd argue that a SOIC-8 programming clip thing would be better. This looks like you need to write a decent amount of code for a computer to talk to it as easily as a FAT-16 SD card.
- ajb 2y agoYou're right; it looks like SD cards implement a protocol on top of SPI. They don't just map the content to SPI addresses. So a flash chip won't look like an SD card to the OS
- Neywiny 2y agoRight. Unsure if it's possible that any SD controller has a secret SPI mode. This seems like a ridiculously niche product. Which is fine but just something to keep in the toolbelt.
