flash memory empty in MAC57D54H -> first programming

Contributor IV

Dear all,

We are working on a new design based on MAC57D54H. We have created our own hardware and are testing first prototypes (all the development phase with evaluation board has been successful and have not found any similar issue). We are surprised since we have found that the microcontroller is continuously executing reset (every 25ms aproximately) and have no possibility to program the flash memory with PEMicro multilink FX.

Is this continuous reset "normal" for a factory device? Is it an indication of something else going wrong?

We are stuck at this phase of development and cannot test prototypes. Could you please give us any hint of what is going on?

Thank you in advance.

Best regards,

Alvaro Martinez
