New development firmware release v1.19.0.b2

We have now released the next weekly development firmware v1.19.0.b2

Important: This firmware uses a different file system that is not compatible with the file system of the stable version (1.18.0 at the time of this post) and there is no migration. All scripts on your device will be lost when switching between the stable and development firmware!

• extmod: handling block devices with block count < 32k

• extmod: updates fsformat() to Format fs with FAT/FAT32 according to device size

• extmod: fix SD card formating problem whe no filesystem is present

• Jenkinsfile: updated file to use Dev branch of IDF idf_dev & make release

• extmod: fix SD card formating problem whe no filesystem is present

New firmware release v1.18.0

New firmware release v1.17.3.b1

This release is mainly here to fix some problems introduced by 1.17.2.b1 a few days ago.
Here's the change log:

• esp32: Switch off the heartbeat LED right after boot.
• esp32/ftp/updater.c: updated function updater_write_boot_info() to write encrypted header (if flash encryption enabled)
• esp32/ftp/updater.c: removed code which checked in ota_write() if chunks are multiple of 16 bytes
• esp32: Use esp_timer_get_time instead of gettimeofday inside ISRs and the idle task (as recommended by Espressif). Fixes crashes caused when using time.ticks_ms() and ticks_us()
• esp32: Only create the LTE task once. Fixes soft reset for the FiPy and GPy.
• esp32: Correct the heartbeat behaviour during soft reset.

Please note that that the function ticks_cpu (https://docs.pycom.io/chapter/firmwareapi/micropython/utime.html#utimetickscpu) has been changed and it now returns a value in microseconds (it's useless to return nano-seconds anyway), so it can be seen as another version of ticks_us but a lot faster. The nano-gateway example has been updated to use this function instead: pycom/pycom-libraries@f344b5a
