PSOC firmware updates via I2C from iMXRT

[mikes603]

Hi Gents,

 Just curious if anyone out there has experience updating PSOC firmware via I2C from a iMXRT MCU?

I've found these docs:https://www.cypress.com/documentation/application-notes/an86526-psoc-4-i2c-bootloader

But it's not so clear to me what path to go down.. is there code someplace where someone has implemented this with the NXP I2C SDK?

Hello mikes.

Assuming PSoC 5LP family discussion here...

For 5LP, I2C bootloader info is available here:
https://www.cypress.com/documentation/application-notes/an60317-psoc-3-and-psoc-5lp-i2c-bootloader

If you scroll down this page, you'll find addition documentation for bootloaders.

I know you're interested in 'host' s/w for iMXRT.  The doc's on bootloaders, contains this information.

I have no experience with iMXRT nor i2C bootloading.  Just wanted to point you towards some info to look at.

Good luck with your project.

edit: BTW, the C source code for a 5LP i2C Host is located in the zip file for AN60317.  If you're feeling ambitious, you could port this code to iMXRT.
