I'm looking for a way to disable timers and interrupts to test whatever or not the FS module is disrupted by running timers, so I would disable interrupts/timers, exec FS routine and re-enable them. Is this possible at the moment?

Afraid not... Interrupts are used for all IO, so it's a bit hard to disable them for any length of time. For example while irqs are disabled, a simple print statement could crash the device.

I seriously doubt this is the problem though as SPI itself isn't really very timing critical. Are you sure it's not just a card that is formatted strangely?

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot
