Hi Ives Liu,

we need to support firmware update in common automobile ECU product via FOTA, when update Cortex-M4's firmware, the Cortex-Axx will be the upper unit, and the Cortex-M4 will be the lower unit, when the upper unit send reset command to the lower unit, the lower unit need to execute this command to reset its own partition, at first we are planning to call scfw api to send message to scfw, then scfw trigger Cortex-M4 Partition to reset, the specific api is sc_err_t sc_pm_reboot_partition ( sc_ipc_t ipc, sc_rm_pt_t pt, sc_pm_reset_type_t type ), but failed to reset this partition, can you tell us the correct way to achieve it in details ?

Thanks

Hi Shuangpeng,

Could you please specify which processor are you using and which BSPs on Cortex-A and Cortex-M sides?

Best regards!
