I have a board which uses the MKL03Z32VFG4 and I'm trying to connect to it using the blhost utility but I receive the following error: Error: Initial ping failure: No response received for ping command. (I have also tried the KinetisFlashTool)
I am using the following pin configuration:
pin 3 - PTA3 LPUART0_TX
pin 4 - PTA4 LPUART0_RX
Searching for similar problems I found Problems entering Bootloader mode. MKL03Z32VFG4.
The response specifies the following connections are required: PTB1 as LPUART0_TX and PTB2 as LPUART0_RX
Can someone confirm whether these are the only pins that can be used with the ROM Bootloader for a UART connection on this device. I am using the Bandgap which requires an external 100nF decoupling capacitor on the Vref pin - PTB2.
Therefore I made my UART connections on PTA3 & PTA4 as noted above.
Thanks for any assistance.
