There is a QEMU port to the i486 under boards/x86/qemu-i486
I am not sure of the state that was left in. I don't think that has
been touched for a while so I would also expect some bit rot.
That port was tested on a retro hardware board. The person that
developed that board reported that i
Has anyone tried to run NuttX on a physical x86 i486 machine?
(I haven't tried yet. Asking first. :-)

Hardly an argument when the basic read and write is the same code and the
remaining could be under #ifdef.
On the other hand there is a lot of bloated code if a board could
be populated with two a more different chips.

Oh!!
So that is the one you used.
I did see that on the menu config, but wasn't sure if it was the one. and I was
halfway through completing the driver when I noticed that option in menu config
anyway, so I went ahead and completed the driver.
Anyway it is working, so no worries there.
Thanks tho
Hi,
I tried using the template that you provied.
I have gotten the mtd partition blocks mounted using littefs. And tried
creating and writing a test message to the file via nsh shell.
The file seems to have been created, and the test message does exist even after
power cycling.
So, now how do
FYI - if you type the / character in menuconfig it will allow you to
search for things (e.g. /MT25 will show two entries relating to MT25
memory - the MTD settings and the actual flash ID of the device you're
using (which will need to exist in the relevant driver code of course -
so with your c

I didn't see MT25QL SPI flash in menu config so I went ahead and wrote one!

Subject: Re: LittleFS Implementation using MTD for NO
I have only ever used NuttX "directly" with my apps running over it
rather than any other middleware or anything, so I can't answer that.
My board has been fitted with a MT25QL01GBBB8ESF, and has worked fine,
so your flash is most likely supported already?

Hi,
I am using MT25QL, 1Gbit series flash memory.
Thanks for the template.
Would running in this format over the middleware running over nuttx also follow
the same approach?

Hi,
What flash are you using out of interest?
But, the basic approach (in or called from your board bringup for
example) is:
spi_flash= sam_spibus_initialize(PORT); /* this call is arch dependent */
if(!spi_flash)
{
/* Do something */
}
#ifdefined(CONFIG_MTD_M25P)
mtd = m25p_initialize(spi_f
Hi community,
I am trying to get littlefs running on a NOR flash memory using the MTD driver,
on a STM32F4 chip.
I had some bottlenecks in the implementation as I am an out-and-out novice when
it comes to Nuttx.
I have written a custom driver for the flash, which is working with MTD, as I
