Does anyone know how to use mb2146-07-e to download firmware to a Fujitsu MCU? I just bought a mb2146-07-e and used PCHELPER software to download the firmware, but it didn't work.USB driver has been installed.
The indicator light is not blinking. And I used an oscilloscope to monitor the single-line UART download port without waveforms.
Have you used this downloader? And, I'm convinced that the software, drivers, and writer are up-to-date. Perhaps I did not pay attention to any details.
Could you please help check:
1. Does the mb2146-07-e is okay? Can you download/debug the FW in Softune IDE via the mb2146-07-e?
2. Which version of PcHelper and PC OS you used?
3. Could you please refer to the "Standalone Programmer module-V1.9.0.e.pdf" document which attached in the download package?
