Difference between EDBG and J-Link (Serial Wire Debug) debugging and flashing
Also, EDBG IC is used inside all other Atmel tools (like Atmel-ICE and variants). They are cheaper than J-Link, but if you already have one then it is irrelevant.   And no, J...

Difference between EDBG and J-Link (Serial Wire Debug) debugging and flashing
EDBG is using SWD protocol. SPI, UART, I2C and GPIO are there for the data gateway, also supported by the EDBG chip. For example, EDBG also appear as a standard USB CDC COM-port,...

SAMD21G burning
Provided that everything else on the board is fine, my guess is that OSCULP32K is really required. It is used for clocking initial CPU boot process and your hardware is in some...

SAMD21G burning
Don't guess. Connect this pin to VCC and try again.   There are a lot of things powered though clamping diodes right now. Plus OSCULP32K is powered from this domain, and it...

Quote from the datasheet: Quote:The same voltage must be applied to both VDDIN, VDDIO and VDDANA. This common voltage is referred to as VDD in the datasheet.

BTW, the whole thing including USB HID, I2C master and some debug UART stuff compiles into ~4K.   Edit: clock initialization is 128 bytes exactly.

No ASF anywhere. All clock setup is done in sys_init() in main.c.   No need to involve bloatware for 20 lines of code.

Here is pretty minimal implementation of USB HID for D21 (also works on D11) - https://github.com/ataradov/dgw

Is I2C really as difficult as it looks on SAM D10?

Here is an example of reading temperature from AT30TS74. GPIO manipulation header can be found here https://github.com/ataradov/mcu-...
