@ -353,6 +353,10 @@ perform the Xous firmware upgrade. This requires running manual update commands,
- Metastability harden I2C & TRNG
- Handle I2C timeouts. The I2C block is sensitive to hardware-specific thresholds, and on some devices it can fail to come up cleanly on boot. This code recovers from that more gracefully.
- Move I/O blocks into always-on domain to avoid clock stoppage during fire and forget I/O operation
- I2C fixes:
- Ensure that the RTC does not interpret line noise during shutdown as garbage by having the very last command issued be a read to the RTC.
- Shut down I2C block after this read happens by disabling it
- Harden the RTC handler such that if junk corrupts the RTC it doesn't loop forever being confused about the junk data.
- More multi-platform support work
- Preliminary Cramium SoC and FPGA targets incorporated
- atsama5d27 target support via PRs from Foundation Devices (thank you!!). Xous is now booting on the ATSAMA5D27-SOM1-EK1 dev board!
