Topic: burn arduino zero's bootloader to SAMD21 with STlink_v2 (Read 1 time) previous topic - next topic


Thanks for the update. Glad to hear you got it going.

The Segger JLink Mini Edu looks like a neat little programmer. (Not for profit use only though).


Can you also use that  JLink Mini Edu within the Arduino IDO to flash a bootloader? Will it show up in the Arduino Software or is it only with AtmelStudio compatible?



Figure Figure 39-10 on page  862 of the datasheetdatasheet for samd21

indicates that SWCLK needs a 1K pullup resistor, I couldn't see it in your schematic.

Note that a pull-up resistor on the SWCLK pin is critical for reliable operations.
