.. this makes reconnecting without a full reset not work.
Because this works on other generations of the esp32 (c2, c3, etc),
apply this behavior only to esp32.
After this change, it's possible to connect multiple times to wifi in
different runs of code.py or the repl after soft rebooting.
Format:
CIRCUITPY_BLE_NAME = My BLE Board
- the length is limited to 31 characters
- for the NRF version it repeatedly truncates the name if it's too long
- the ESP version defaults to "nimble" if the name is too long
A recent build failed. The original error seemed to be during ci_fetch_deps
where a build message said
```
fatal: reference is not a tree: 346c936e14c6ea3a8d3d65cb1fa46202dc92999d
fatal: Unable to checkout '346c936e14c6ea3a8d3d65cb1fa46202dc92999d' in submodule path 'extmod/ulab'
```
(along with other problems), but this step didn't signal failure to
github actions.
By adding the check= parameter, a failure of the subprocess will cause
a CalledProcessError to be raised, which will make ci_fetch_deps exit with
nonzero status. In turn, this should let Actions understand that something
went wrong with this step, instead of waiting for some subsequent step(s)
to go wrong.
rather than setting the heap size statically, micropython allocates
the biggest contiguous chunk possible, but in no event more than half the
total internal sram. On esp32 this gives 123728 bytes of `gc.mem_free`
in the repl.
Also, change error handling so that the esp-idf error number
is shown in the traceback in the case of an error.
This allows scanning & connecting to work. I didn't try requests yet.
esp32 places the psram start at SOC_EXTRAM_DATA_LOW and it can extend
up to SOC_EXTRAM_DATA_SIZE. This is different than esp32-s2 and later,
which place the end at EXTRAM_DATA_HIGH and the limitation of
SOC_EXTRAM_DATA_SIZE was not previously identified as important.
Additionally, the esp32 has a reserved area within himem which was
not being accounted for.
With this change, the Feather ESP32 V2 feather can be used via thonny,
and the other "quick memory corruption tests" I was performing
also all succeed instead of failing.
Before this change, the incorrect address being used for spiram was
0x3fa00000..0x3fc00000 (2MiB). Now, it's 0x3f800000..0x3f9c0000 (1.75MiB)
due to the reserved area and the changed start address.
This is intended to be a no-effect change for other espressif chips besides
original esp32.
