Pankaj,

Yes, 'Modes can be changed at runtime'. Please see the 'PRU-ICSS HSR-PRP DAN Firmware Data Sheet' in docs/ folder.

Pankaj,

Please refer to RedPru1DmemInit() in hsrPrp_red_config.c to update the HSR_MODE

#ifdef ICSS_PROTOCOL_HSR
#ifdef HSR_MODE_H
#define HSR_MODE_INIT MODEH
#endif /* HSR_MODE_H */
#ifdef HSR_MODE_N
#define HSR_MODE_INIT MODEN
#endif /* HSR_MODE_N */
#ifdef HSR_MODE_T
#define HSR_MODE_INIT MODET
#endif /* HSR_MODE_T */
#ifdef HSR_MODE_U
#define HSR_MODE_INIT MODEU
#endif /* HSR_MODE_U */
#ifdef HSR_MODE_M
#define HSR_MODE_INIT MODEM
#endif /* HSR_MODE_M */
#endif /* ICSS_PROTOCOL_HSR */

*((uint16_t *)(((((ICSS_EmacHwAttrs *)
icssEmacHandle->hwAttrs)->emacBaseAddrCfg)->dataRam0BaseAddr) + LRE_HSR_MODE)) =
HSR_MODE_INIT;
