ipc_acquire() function

Acquires IPC structure. PSoC6 uses IPC structures for inter-core communication. Same IPCs are used to invoke SROM API. IPC structure must be locked prior to invoking any SROM API. This ensures nothing else in the system will use same IPC thus corrupting our data. This function locks the IPC.

Syntax

static int ipc_acquire(struct target *target,     char ipc_id);

Arguments

target

current target

ipc_id

ipc_id IPC index to acquire. IPC #2 is dedicated for DAP access

Return value
