Hi Tim, Congratulations! We are happy to see your progress with NuttX. If you want to help future "Tim"s please right a small documentation about it. You can create it at: Documentation/guides/eeprom_spi.rst BR, Alan On 8/25/21, Tim Hardisty wrote: > My board is now correctly registering

My board is now correctly registering the SPI instance and binding the relevant SPI and CS to the SPI Flash driver. It was an uphill struggle, but thanks to all your various suggestions I have got there and learned more than I wanted to! Next hurdle is to trawl through other boards to learn

There is support for MT25Q128 and I have now added the MT25Q256 It is in nuttx/drivers/mtd/m25px.c and I will add to the list of PRs once I have everything sorted on my board. Subject: Re: nxfss on MT25Q nor flash BTW, do we have a driver for MT25Q? I can't see one. Is it compatible

that is the best and usual way to get documentation about nuttx you need some grep-fu the system.map trick is a generic debug technique that you can't invent if someone else doesnt tell you about it :) sebastien Le 24/08/2021 à 18:57, Tim a écrit : No, it's not in the system map. Having

Hi Tim, It is not your fault, it is fault to NuttX complexity. We need to improve it, I think NSH_ARCHINIT should be enabled by default. NuttX is full of unnecessary traps that let users to fall into all the time. BR, Alan On 8/24/21, Tim wrote: > No, it's not in the system map. Having now

No, it's not in the system map. Having now searched for it I see there's a possibly useful example in stm32_appinit.c so I will wade through that. How was I supposed to know what to look for!!?? >Ok, did you open your System.map and searched for m25p_initialize() ? > >Few days ago I gave

Hi Tim, It seams like MT25Q uses the m25px.c driver, so I assume you are enabling the CONFIG_MT25Q_MEMORY_TYPE right? Next you need to configure our board SPI CS pin, please take a look at: arm/stm32/mikroe-stm32f4/src/stm32_spi.c Then before try to setup the NXFFS you need to confirm that the

Does anyone have any pointers on how to setup nxfss (or any filesystem for that matter) on an MT25Q nor flash? I cannot find any code for any other boards that makes any sense to me and I feel this should be a pretty basic thing to want to do? I believe I have set up all the SPI stuff and now
