Set this value to -1 if the ULP RISC-V I2C read and write APIs should wait forever. Please note that the tick rate of the ULP co-processor would be different than the OS tick rate of the main core and therefore can have different timeout value depending on which core the API is invoked on. endmenu config ULP_SHARED_MEM depends on ULP_COPROC_TYPE_LP_CORE hex default 0x8 help Size of the shared memory defined in ulp_lp_core_memory_shared.c.

This option can help reduce the LP core binary size by not linking printf functionality from RAM code. Note: For LP ROM prints to work properly, make sure that the LP core boots from the LP ROM. endmenu # Ultra Low Power (ULP) Co-processor
