1. Support Nuvoton targets:
- NUMAKER_IOT_M263A
2. Change storage to NUSD (SD card in SDIO bus mode) from SD (SD card SPI bus mode)
(1) Add COMPONENT_NUSD.lib.
(2) Add component NUSD (target.components_add).
(3) Change default BlockDevice to NUSD:
Override BlockDevice::get_default_instance (nusd.provide-default-blockdevice).
Required since mbed-cloud-client 2.1.0 (arm_uc_blockdevice_ext) or in:
mbed-bootloader/modules/storage/pal-blockdevice/source/arm_uc_pal_blockdevice_mbed.cpp
(4) Enable kvstore with blockdevice type being "other".
i) Override get_other_blockdevice() (nusd.provide-kvstore-other-blockdevice).
ii) Configure storage type to "FILESYSTEM".
iii)Configure file system type to "LITTLE".
vi) Configure block device type to "other".
v) Configure external size to 64MiB, which cannot overlap with update-client.
storage-address/update-client.storage-size.
3. Change back UARTSerial tx/rx buffer size from 1024/1024 to 256/256. This can reduce
memory footprint by (1024 - 256) * 2 = 1.5KiB. Because this configuration influences
both ESP8266 and default console (platfrom/mbed_retarget.cpp), memory reduction can
achieve 1.5KiB x 2 = 3KiB.
4. Enlarge ESP8266 'send tcp data' timeout on Nuvoton targets
Pelion connection has some failure rate with this. Enlarging ESP8266_SEND_TIMEOUT
can just relieve the issue. A ticket has raised to address it:
ARMmbed/mbed-os#11544
