Checking SPI bootloader support on CY8C4025LQI-S412

fj0176bu_1406951 Aug 5, 2018 11:05 PM

I want to know how to configure PSOC 4000S to support Boot loading function using SPI.

I checked the SCB block and it can support such function but only I2C.

I want to use a SPI flash to automatically download the code instead of through MCU.

Is there any good way to do it?

Yes, SPI bootloading is possible in PSoC 4000S. However, the kit does not have inbuilt USB-SPI bridge. Please use external USB-SPI bridge such as TrueTouch Bridge for bootloading.

Thank you for your reply.

I want to use SPI for downloading the FW directly. I can’t use USB SPI
bridge.
Also, can you send app note you show how to configure the SCB as a SPI
bootloading?

What is the SPI bootloader host in your application?

There is no application note on PSoC 4000S SPI bootloader. Please refer AN84401 - SPI Bootloader to get started.

I read AN84401.
Just a quick question, in the doc , it mentions only PSOC3 and PSOC5L.
Can it be supported in PSOC4S?

Yes, you can configure SPI component and bootloader component as elaborated in AN84401.
