# Raspberry Pi4 bootloader EEPROM release notes
USB MSD boot also requires updated beta GPU firmware. Please read
https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2711_bootloader_config.md
## 2020-07-09 Promote 2020-06-15 to STABLE
* Increase port power off limit to 5 seconds.
* Increase the port power off default to 1 second. This seems to cover most
commonly seen USB MSD devices which require the USB port power to be disabled
after the USB HC chip is reset.
* Reset activity LED after SPI access to reduce the number of spurious LED flashes.
* Add SPI error diagnostic error code (3 long 1 short) if SPI commands timeout.
(So far this failure has not been observed on failed boards)
## 2020-06-17 Promote 2020-06-15 to STABLE
* Promote the latest beta EEPROM and recovery.bin to stable and
feature freeze USB MSD support until a production release is ready.
