Revision as of 15:51, 17 October 2022

Revision	Changes
0	Initial Release
1	Added Sleep mode Blinks blue LED in low power modes. Sleep mode does this, as well as USB device connected with no power on the main VIN.
2	Added support for REV D boards. Earlier boards will continue to use REV 1 only.
3	Fixed Silabs not responding on I2C after sleep mode is used.
4	This revision prevents USB suspend from putting the silabs into a low power state. In previous versions if a USB cable is connected, but the serial console is not open, then some operating systems will issue a USB suspend. This would prevent communication over the I2C to the silabs.
5	Initial port to Renesas RA4M2 series.
6	Initial support for sleep mode
7	Support for in the field updates USB Serial number set to board Serial/MAC address Sleep mode bug fixes
8	Prevent RTC/SRAM writes as power is dropping to prevent corruption USB CDC ACM fixed issues with dropped characters. REV 8 will not drop any data in TX/RX at 115200 baud.
