CY8CPROTO_062_4343W does not support bootloader?

[JanneKiiskila]

Description

Cypress board does not support bootloader according to targets.json, is there a special reason for that or should it be enabled? Without bootloader support is it not possible to enable Pelion Device Management Firmware update -feature.

Ref:
https://github.com/ARMmbed/mbed-os/blob/master/targets/targets.json#L8332-L8354, especially line https://github.com/ARMmbed/mbed-os/blob/master/targets/targets.json#L8354.

• We can see target CY8CKIT_062_WIFI_BT_PSA is supporting bootloader.
• However, for target CY8CKIT_062_4343W bootloader is not enabled.

The lack of bootloader will disable generation of APPLICATION_ADDR, which in turn will then block the firmware update from getting compiled.

do you mean "CY8CPROTO" instead of "CY8CKIT"?

I found that with these lines added to the CY8CPROTO_062_4343W configuration in targets.json, then a bootloader and application can be built.

        "bootloader_supported" : true,
        "mbed_rom_start" : "0x10002000",
        "mbed_rom_size" : "0x1F6000",
        "sectors": [[268435456, 512]]		

After more testing, I can make a PR to be evaluated by Cypress.
