S32K3 SPI or I2C bootloader

[vinaykl]

Hello Team,

We are working on S32K3 microcontroller. But we are not able to find any bootloader examples for S32K3 using SPI or I2C interface. 

Kindly let us know if there are some example code which uses SPI or I2C for Bootloader for S32K3 microcontroller. We are using this for Firmware upgrade.

Thanks and regards,

Vinay

Hi @vinaykl 

I summarized what we provide here in this post:

https://community.nxp.com/t5/S32K/Firmware-update-in-S32K312-via-CAN/m-p/1709934/highlight/true#M263...

We don't have a bootloader directly for SPI or I2C.

Hello lukaszadrapa,

Thank you for your response.

I am very happy that responses are very fast now adays from NXP. 

The processor whatever we are using doesn't have any CAN interface. It only have SPI and I2C interfaces. So we have to go with these two interfaces. Is there any other ways or any other commands which we can rely on SPI or I2C rather than CAN interface.  

Thanks and regards,

Vinay

Hi Vinay,

Our RTD contain I2C and SPI drivers. There are both Autosar MCAL layer and lower Ip layer if needed. SW examples are included in the RTD package.

As I wrote, we don't have I2C or SPI bootloader, so it will be necessary to develop own solution.

Regards,

Lukas
