Kudos from me also, and best of luck getting that product released!
If I may suggest, perhaps at some future NuttX workshop, you could present
about how NuttX is being used in automotive.
Cheers

My NuttX journey started in earnest about a year ago, after an enforced pause
for personal reasons. The processor on my board is ATSAMA5D2. In the last year
I have submitted (nearly all) merged PRs for this processor:
- mcan
- flexcom SPI
- ClassD audio
- SPI DMA
- flexcom USART
- efuse support
Thanks for replies.
Alan – your video (which I had watched!) is for AT24 I2C EEPROM and it can’t be
done in the same way for SPI EEPROM with no device ID to read back We had this
same conversation a year or 2 ago when I was very new to NuttX, and I even
found an archived email saying I’d sor

Sure you can. That is a character device, not an MTD or block driver,

Hi Tim,
There are two ways to access EEPROM on NuttX, one is using this
character driver that you are using and the other is accessing it as a
MTD.
I created a video tutorial some years ago explaining how to do it:

Keep in mind that using MTD with I2C
Hi,
This eeprom is not an mtd device, it is too small for any filesystem, usually.
So it's just a character device that makes the eeprom appear as a fixed size
file.
If you need an eeprom mtd, the driver could be extended to make it behave as a
mtd device.

Could have sworn I had this working a year or 2 ago but it's stumped me today...

Unlike at25_initialize, the ee25xx_initialize doesn't return mtd_d
