Open SDA Firmware Question

wj_kwak — Thu, 23 Jul 2026 06:35:38 GMT

I purchased the FRDM-A-S32K358 development board and checked the JTAG port for changing the firmware on the MK26 chip responsible for Open SDA. If I accidentally install the firmware on J13, I will need to obtain the Open SDA firmware. In this case, can I obtain the firmware by requesting it via a support ticket?

Hi @wj_kwak

If the MK26 OpenSDA device has been overwritten via J13, the standard OpenSDA update procedure may no longer be applicable, since it relies on a functioning OpenSDA bootloader. The OpenSDA recovery firmware is not generally distributed as a standalone programming image.

The OpenSDA firmware and bootloader are PEmicro technology rather than NXP-developed software. PEmicro provides the firmware updates, bootloader update applications, and related support for OpenSDA.

Therefore, if the MK26 has been erased or reprogrammed via JTAG/SWD and the OpenSDA bootloader is no longer functional, PEmicro would be the primary contact for recovery guidance and firmware availability.
