+Board ID:         0x4b01 (SDR50)
+Board revision:   0x0
+FPGA revision:    2021-10-08 15:38:12 (upgrade rev: 2023-06-27)
+FPGA status:      operational
+FPGA flash:       Infineon/Cypress(32 MB)
+Software version: 2023-09-09
+DMA:              1 ch, 32 bits, SMem index: Off
+DNA:              [0x19296160552233052]
+Serial            ''

+
+# Patch your FPGA
+
+To patch your FPGA, first get the ORS 2023-09-09 bitstream from Rapid.Space, then:
+
+root@orsXXX:~/ors-root-access/flash-fpga# ./init.sh
+root@orsXXX:~/ors-root-access/flash-fpga# ./patch-FPGA.sh
+
+Then do a hard reboot by unplugging the ORS and replugging it (make sure not to unplug it from the POE cable)
