Re: Mininal Port's Garbage Collection

Does anything prevent you from looking into the stack trace and/or running gdb on it?

Re: Custom port A9G module: help wanted

I have a display over SPI now. It is quite slow. The main reason, I believe, is python library which drives it pixel-by-pixel.

https://github.com/boochow/MicroPython-ST7735

What is the best way to speed it up?

Re: Custom port A9G module: help wanted

It is just something that I was considering implementing. I won't for now then.

Re: Custom port A9G module: help wanted

I am happy to announce that [the port](https://github.com/pulkin/micropython/blob/master/ports/gprs_a9/README.md) is advancing. In terms of hardware, a number of things are working reliably including GPIO, GPRS network, SMS, file IO, system and power things. Now I am looking at `micropython.native/v...

Re: ulab, or what you will - numpy on bare metal

Awesome project. Regarding possible developments, having more of `numpy.linalg` stuff (eig, svd) would be really cool and relevant.

Re: Custom port A9G module: help wanted

Exactly. I have a code which compiles and runs but since this is my first asm code I have no idea whether it will actually work in the wild.

Re: Custom port A9G module: help wanted

Can you give an example of the code that would cause a root pointer to stuck in the registers? I tried the following one with no success: ptr remains inside the memory. void gc_stress_test(void) { volatile int delta = 0; void* ptr; // Some significant allocation ptr = gc_alloc(400000, 0); // Make pt...

Re: Custom port A9G module: help wanted

Well, the question is how much contiguous memory can be allocated. I will stick to 512k (well, a binary search can be applied here but I do not think it is import right now). The good news is that mp finaliser is working! Deleting a file pointer and calling gc.colllect will actually close the file! ...
