The BoSL board rev 0.5.0 arrived and its time to test how it works. Lets jump into it!
Straight out of the packet:
- Plugging in a battery the idle current 840 µA.
- Touching a screw driver to the F1 TEST pad lights up the test LED.
- When the WDT_EN jumper is closed the current jumps up to ~10 mA. This seems appropriate, if it enables the voltage on VPP.
From now on WDT_EN will be closed
- Voltage is good on 3V3 and VBAT. Measured (3.370V and 3.941V respectively).
- The bootloader could be programmed using the normal process of Arduino as ISP. Specifically I used the [[1]] board library and selected the ATmega640 board. I then used BOD: 2.7V, bootloader: yes UART0, clock: external 8MHz, EEPROM: EEPROM retain, compiler LTO: LTO disabled, pinout: AVR pinout.
- Idle current now 18 mA.
- I then plugged in the board via USB and it was recognised as a serial port.
- Programs could be uploaded via USB now, the serial monitor analogue read, and the RX,TX, LED, and USB, LEDs work.
Errors:
- WDT_EN is not the correct name for the jumper as the WDT is disabled when closed. It should be not WDT_EN
