VH-109_1.2.8-01222025

Notes

CRITICAL UPDATE

• This is a continuation of the flash corruption discovered in November of 2024.

  • Root cause failure analysis was completed and discovered an errant process writing to flash at a period of once every 30 seconds. In extreme circumstances, the NAND flash controller could glitch upon a power event (brownout or during power off), accidentally writing to critical regions of memory resulting in memory corruption that could disable the radio.

VH-109_1.2.7-01162025

Notes

• Team Access Point behavior

  • Fixed bug when placing radio into "Access Point Mode" disabling the 2.4 GHz radio once a robot connects to the 6 GHz radio

  • Renamed the 2.4 GHz SSID when in "Access Point Mode" to "FRC-AP-XXYY-SUFFIX", making it more clear on which device you're connected to

VH-109_1.2.5-11032024

Notes

• CRITICAL UPDATE

  • Flash memory corruption has been observed on a number of radios affecting the factory burned calibration and regulatory limits partition.

    • A mitigation has been developed addressing this potential corruption.

    • It is recommended that teams update to this firmware as soon as possible to prevent the radio from becoming inoperable without manufacturer support.
