help
Select the workaround strategy. Note that the strategy for precompiled
libraries (libgcc, newlib, bt, wifi) is not affected by this selection.
Unless you know you need a different strategy, it's suggested you stay
with the default MEMW strategy. Note that DUPLDST can interfere with hardware
encryption and this will be automatically disabled if this workaround is selected.
'Insert nops' is the workaround that was used in older esp-idf versions. This workaround
still can cause faulty data transfers from/to SPI RAM in some situation.
