My design as the below
Flash - W25X20CL
P0.0 - SCK
P0_3 - SPI CS
P0_5 - MOSI
P0_6 - MISO
I select P1_0 as TX P1_1 as RX.
Now I find it's sames can't download firmware.Can I fly line the P0.0(it connect Flash SCK pin now) as uart
and down firmware through uart (P0.0,P0_1,57600Bd)?
or if there have any other methods to solve this problem.
