Paul Sokolovsky 5f7ce2a1ca esp8266/modules/flashbdev: Reserve one sector for native code storage. 2017-05-12 16:08:54 +03:00
Damien George e343bea6e7 esp8266/modules/flashbdev: Change RESERVED_SECS to 0.
This effectively reverts the change that introduced this new constant.
The reason is so that users do not need to rebuild the filesystem on
their modules when upgrading the firmware.

Users can change RESERVED_SECS by hand if they need the feature, and in
future firmware it may default to a non-zero value.

Damien George cc7e48fdc8 esp8266/modules/flashbdev: Remove now-unused function set_bl_flash_size. 2017-01-06 16:22:53 +11:00
Paul Sokolovsky 4a72294d7d esp8266/modules/flashbdev: Remove code to patch bootloader flash size.
This code is no longer pertinent for some time - since switchover to
SDK2.0, there must be correct flash size set for bootloader, or there's
a risk of flash data corruption. And indeed, the correct flash size is
by default auto-detected by esptool.py 1.2.

Damien George bae7798f1e esp8266/modules/flashbdev: Add RESERVED_SECS before the filesystem.
Starting at esp.flash_user_start(), the reserved sectors are for general
purpose use, for example for native code generation.  There is currently
one sector reserved as such.

Paul Sokolovsky e6af94d13b esp8266/modesp: Add flash_user_start() function.
As we're looking towards adding OTA support, calculation of a FlashROM
area which can be used for filesystem (etc.) may become complex, so
introduce C function for that. So far it just hardcodes current value,
0x90000. In the future the function may be extended (and renamed) to
return the size of area too.

Paul Sokolovsky 3c9510d767 esp8266/modules/flashbdev: Start filesystem at 0x90000.
To accommodate growing firmware.

Paul Sokolovsky ca59f5f208 esp8266/flashbdev: Reserve extra sysparam sector for SDK 2.0.0 compatibility. 2016-08-06 15:21:49 +03:00
Damien George db80c0ed46 esp8266: Enable frozen bytecode, with scripts in modules/ subdir.
To start with, the critical scripts _boot.py and flashbdev.py are frozen
to improve performance and reduce RAM consumption.

Saves about 1000 bytes of heap RAM for a bare boot with filesystem.
