NuttX is in compliance with SDA 2.0 specification, so the SD card capacity limit is 32 GB.

Hi @Tony-Prince

Do you use SD card in FAT format?

Have you tried to isolate and verify the functions alone?
Audio without GNSS, GNSS without Audio etc?

Hi @Ben-eaton

In the folder sdk/tools/ you will find a script called callstack.py
You can use this tool to analyze your stack dumps.

spresense/sdk/tools$ ./callstack.py 
Usage: python ./callstack.py <System.map> <stackdump.log>

What code are you running?

Hi @Ben-eaton

Would you like to share your code maybe I could have a look?

Hi @thedubdude

I installed the FastLED library from through the Arduino IDE . The FastLED lib seem to have very architecture and environment dependent code that has not been ported to Spresense/Nuttx.

So you, or somebody, will have to port it before it will build for Spresense.

Hi @Cameron-R-MANN,

Regarding WIN10 + MSYS, try deleting these folders:

• ~/spresense/nuttx/include/arch
• ~/spresense/nuttx/arch/arm/src/board

Then run "make distclean". I hope it will help!

Hi @Cameron-R-MANN

I played around with the drivers you linked to.
And found that if you change the following line in Adafruit_SPITFT.h

//void         initSPI(uint32_t freq = 0, uint8_t spiMode = SPI_MODE0);
void         initSPI(uint32_t freq = 0, uint8_t spiMode = SPI_MODE3);

or even better in Adafruit_ILI9341 line 189:

initSPI(freq);
to
initSPI(freq, SPI_MODE3);

you should get the desired result.

Please give it a try and see if it works better.

Hi, in the past I have used a ST7735 display with the standard Arduino drivers for that chip. And I remember that the drivers used specific register writes when used with original Arduino that didn't work with Spresense.

If you have a look at:
https://github.com/TE-KarlKomierowski/TFT/commit/ffbab7269e7ef7470f10a6f63fd077cfa46db180

You can see that I made macros of the chip select settning/unsetting functions.

Some designs ILI934x are very voltage sensitive, if you run them at 5V gpio voltage they don't work. So the GPIO voltage has to be 3.3v.

It would help a lot if you could provide the code you are trying to run and also point to the tft driver you are using. And also the wiring diagram.

Hi @sgstreet

As for now the two documents on this page: https://www.sony-semicon.co.jp/products_en/spresense/ are all there is for chip documentation. I can try to see if I can get any information on if there will be an update soon.
