It fixes a crash that occurs if the flash doesn't start correctly and the original spot isn't reached. add pin claiming to devices 2018-08-31T22:38:05+00:00 Dan Halbert halbert@halwitz.org 2018-08-31T21:46:03+00:00 urn:sha1:9ea809bef73e6862103cd71802803122e97bf80b Compress all translated strings with Huffman coding. 2018-08-17T00:40:57+00:00 Scott Shawcroft scott@tannewt.org 2018-08-16T01:32:37+00:00 urn:sha1:de5a9d72dcdaacdd5048195cd5bab007f4b2baef This saves code space in builds which use link-time optimization. The optimization drops the untranslated strings and replaces them with a compressed_string_t struct. It can then be decompressed to a c string. Builds without LTO work as well but include both untranslated strings and compressed strings. This work could be expanded to include QSTRs and loaded strings if a compress method is added to C. Its tracked in #531. Support internationalisation. 2018-08-07T21:58:57+00:00 Scott Shawcroft scott@tannewt.org 2018-07-31T23:53:54+00:00 urn:sha1:933add6cd833bb6ba6682ad2b6eb478871415ff5 Allow for resizing the stack area. 2018-07-31T12:18:23+00:00 Scott Shawcroft scott@tannewt.org 2018-07-25T12:06:30+00:00 urn:sha1:12cf5e51c29a5a74ced59c6c89af44e93e2de815 Add basic memory allocation outside Python runtime 2018-07-31T12:18:03+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2018-05-24T20:12:18+00:00 urn:sha1:777542c716e07e78439c3c6bbf442722ebaaecc6 This allows for the heap to fill all space but the stack. It also allows us to designate space for memory outside the runtime for things such as USB descriptors, flash cache and main filename. Fixes #754 Mark pointers in cpu registers as in use. 2018-07-03T12:45:50+00:00 Scott Shawcroft scott@tannewt.org 2018-06-28T17:36:28+00:00 urn:sha1:ec78d3cefdd98b317a01840e172e7453013ada0c This prevents bugs where gc_collect is called from C code that did a recent allocation.

Closes: #904 main: Explicitly set the stack top based on _estack 2018-06-06T03:04:55+00:00 Jeff Epler jepler@unpythonic.net 2018-06-06T03:04:30+00:00 urn:sha1:a4e06bd998a1fb2d2dd209524d8ccd69b18712e6 .. setting it based on the ad-hoc stack pointer calculation of mp_stack_ctrl_init() meant that the stack used above main() counts against the 1KiB safety factor that the mp_stack_set_limit call tries to establish. It turns out, at least on M4, that over half of the safety factor is used up by stack-above-main()! In the case of the basics/gen_stack_overflow.py test, which blows the stack on purpose, it turns out that gc would be called while handling the "maximum recursion depth exceeded" error, and this needed more stack than was left. Closes: #900
