Remind that this PR relies on ARMmbed/mbed-os#11594 |
It was a good test for the CI, it should have reported build failures :) |

Test run: FAILEDFailed to build following targets: posted-by-tag: https://jenkins-client.isgtesting.com/job/mbed-os-example-pelion/ |

For ARMC6 build failure, it relies on ARMmbed/mbed-os#11594. |

We find an issue with M2351. M2351 is a TrustZone target. When any of memory partition, IP security attribute, and secure gateway library in secure program (in mbed-os tree) is changed, bootloader needs rebuild accordingly. This increases maintenance effort in this repo. Please suspend this PR. |
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:
- NU_PFM_M2351_NPSA_NS
2. Support M2351
(1) Use pre-built secure image/lib
(2) Build by running:
$ mbed compile -m NU_PFM_M2351_NPSA_NS -t ARMC6
3. 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.
4. 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.
5. 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
6. 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 NU_PFM_M2351_NPSA_NS target renaming and combined build
- mbed-os 5.14.? (or afterwards) to support NU_PFM_M2351_NPSA_S default secure program which has partitioned memory for Pelion application
