Assume that an SPI flash chip is represented as /dev/spidev. How do I enable that flash chip's power-cycle write protection?

  • have you searched the phrase `Enable SPI flash device power cycle write protection` - to me, a layman, it seems like this depends on the actual device itself, there is no generic method – Jaromanda X Mar 09 '23 at 02:57
  • @JaromandaX It's a common feature of SPI flash devices. – Melab Mar 09 '23 at 03:28
  • are you talking about hardware or software methods? – Jaromanda X Mar 09 '23 at 03:36
  • @JaromandaX Confusingly, there are `software write protection` and `hardware write protection`, but both are mechanisms of the SPI flash chip. – Melab Mar 10 '23 at 00:55
