Cypress Bootloader API

[Anonymous]

Hello everyone,

   

I am fairly new to the PSoC programming and have to create a boot loader application. Is there anyway that I can learn more about the Boot loader API functions?

   

Thanks in advance,
Kaan

There is. All standard components in PSoC Creator have, when you double click them, a button "Datasheet" on the bottom-left.
Those datasheet always have a section about the API. This also applies to the bootloadable/bootloader components.

I've read that but the API section is very general and doesn't mention all of the functions. Even though the function names are pretty self explanatory and that I can figure them out by trying, I wondered if there was any external source that I can read to hasten my prototyping process.

Merhaba! And welcome in the forum. cetin

   

All APIS are named and described in the datasheet, what exactly do you need more from a bootloader except loading and programming a new image into the chip and let it run.

Merhaba Bob,

   

I need the bootloader to go and check a web server for updates and update the current image with the update. Basically firmware over-the-air.

   

I am fairly new on this topic so I wanted to learn more about the bootloader functionalities before diving head on.

There are examples on how to build your own BootLoader. For the sake of security I would suggest to do  OTA with an intermediate step: Putting the new firmware into a separate eeprom or FRam, always having a running (older) copy and when the update fails (for whatever reason) fall back to the older copy.
