PRU-ICSS Firmware Revision¶
Platform | Build | Firmware Header Location |
---|---|---|
AM335x,AM437x,AMIC11x | [1.7] [0.11.0] | protocols\profinet_slave\firmware\v1.0 |
AM57x | [7.7] [0.11.1] | protocols\profinet_slave\firmware\v2.1 |
Fixed Issues¶
Record ID | Platform | Details | Comments |
---|---|---|---|
PINDSW-1651 | AM57xx,K2G | Firmware discards some valid CPM frames with cycle counter zero | None |
PINDSW-2061 | AM57xx,K2G | Application forwards the Sync packets on port even if the End of Sync Domain is selected | None |
PINDSW-2214 | AM335x,AM437x, AMIC11x,AM57xx,K2G | IRT communication stability issues in multi-board chain in presence of Scalance 204 IRT Switch | Issue was fixed by the Scalance 204 IRT Switch firmware update |
PINDSW-2249 | AM335x,AM437x, AMIC11x,AM57xx,K2G | Application is not restoring data exchange when Netload Faulty tests are ran in overnight regression mode | PDK update fixed the issue |
PINDSW-2262 | AM335x,AM437x, AMIC11x,AM57xx,K2G | Application is not sending out LLDP frames and basic DCP issues OOB | User now has the option to write default value to Flash. See details in User Guide: |
PINDSW-2345 | K2G | Automated RT Tester PDEV_RECORDS test case fails for ICSS1 | PDK update fixed the issue |
PINDSW-2352 | AMIC11x,K2G | SPIRTA PTCPTimeoutFactor test case failure | Issue was caused by the incorrect timer clock source configuration. AMIC11x application now uses DMTIMER4 and K2G uses GPTimer1 for accurate SYSBIOS ticks |
