Hi
I am debugging the S32K144 and configuring the MCU and Prot using EB. Put PTB5
Configured as CLKOUT with a frequency of 4MHz. Then the program cannot be downloaded again (debug). But after I power it back on, I measured that PTB5 is still 4MHz output. I don't know what caused this.
Hi,
Is this the only pin you used?
I mean, are JTAG/SWD pins and the reset pin in the default configuration?
Thanks,
Daniel
Hi.
YES,JTAG/SWD pins and the reset pin are in the default configuration, i just configure the PBT5 as the output for CLKOUT.
Thanks,
Hi,
Hard to say what could be wrong.
To exclude a SW issue, have you tried the same code on another board?
Can you share the code?
Regards,
Daniel
Hi,
I have solved this problem because the chip is locked
thank you very much!
