            Select place to store core dump: flash, uart or none (to disable core dumps generation).

            Core dumps to Flash are not available if PSRAM is used for task stacks.

            If core dump is configured to be stored in flash and custom partition table is used add
            corresponding entry to your CSV. For examples, please see predefined partition table CSV descriptions
            in the components/partition_table directory.

            Size of the memory to be reserved for core dump stack. If 0 core dump process will run on
            the stack of crashed task/ISR, otherwise special stack will be allocated.
            To ensure that core dump itself will not overflow task/ISR stack set this to the value above 800.
            NOTE: It eats DRAM.
