My computer recognizes my board only as BOOTLOADER

[IuliaB]

Hello! My S32K144 wont be recognized from my computer since I updated my opensda in booatloader and loaded an example application to test my board. Since then, I cant see it on my desktop just when I put it in bootloader mode

Hi IuliaB,

I don't have S32K144EVB on hand, please refer to the SDA_INFO.HTM of S32K146EVB. You can check the version of application (APPVER) :

OpenSDA Firmware (MSD & Debug)

Firmware Apps (.zip file).

The application (MSD-DEBUG-EVB-S32K144_Pemicro_v119.SDA) can be found after download it.

If the "APPVER" value="1.19", then the application of OpenSDA has been correct updated. Then it might be due to the reset signal from the S32K144 causing OpenSDA to enter Bootloader mode. Please try to disconnect J107, and then plug USB cable at J7. The S32K144EVB should not Enter OpenSDA Bootloader Mode. After connect J107(P5V_SDA_PSW-P5V0) and program S32K144 with a correct project, the reset should not output low voltage anymore.

If the "APPVER" value="0", then the application of OpenSDA has not been correct updated. Please Load an OpenSDA Application again.

Best Regards,
Robin
