There was a problem hiding this comment.
Any reason the bootloader is this large? I presume this has to align to quite large sector sizes?

Not related to sector size. 32KiB is too just fit. Reserve space for normal build or even debug build.

Follow other target like NUCLEO_F411RE for configuring external storage size. Besides, it could be used for user application. |

Based on mbed-os-pelion-example master/mbed-bootloader 4.1.0/mbed-cloud-client 4.0.0,
support Nuvoton targets:
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
5. Requirements for mbed-os version:
- mbed-os 5.13.0 (or afterwards) to support kvstore with block device type being "other"
- mbed-os 5.13.1 (or afterwards) to fix 'undefined pal_plat_osEntropyInject(...)' error
- mbed-os 5.14.0 (or afterwards) to support NUMAKER_IOT_M263A
