Communication Protocols Support in PSoC® 3, PSoC 4, and PSoC 5LP Bootloader Component - KBA84744

Version: *D

Translation - Japanese: PSoC®3、PSoC 4、およびPSoC 5LPブートローダーコンポーネントでの通信プロトコルのサポート - KBA84744 - Community Translated (JA)

Question:

What are the communication protocols supported by PSoC 3, PSoC 4, and PSoC 5LP Bootloader Component? What are the different bootloader hosts that can be used with PSoC 3, PSoC 4, and PSoC 5LP?

Answer:

The various communication protocols supported by the Bootloader Component (v1.50 in PSoC Creator4.0) are :

For information on support for custom communication protocols, see the “Adding Bootloader Support” topic in the Component Author Guide (PSoC Creator > Help > Documentation > Component Author Guide) .

Note: PSoC Creator supports bootloading through SCB-based UART and SPI Components in PSoC 4.

1 PSoC 3 can be used as a bootloader host with modifications in the PSoC 5LP-based bootloader host project. However, because PSoC 3 has much lower flash size, a bootloadable project that works with PSoC 5LP may not work with PSoC 3 unless the flash space required by the bootloadable project can fit into PSoC 3’s flash. Therefore, it is recommended to use PSoC 5LP as the Bootloader host instead of PSoC 3.

2 The Application note also explains how to create a Windows-based bootloader host.

3 Application note is not available.

4 Only applicable for PSoC 4200L devices. Application note is not available.
