Swd ack
SpletYou can do swd with spi if you use spi with fifo and variable bit size. At least no need to manipulate the gpio except disabling mosi when reading back data. No bitbang needed. The tricm is to group the turnaround bits and see 5 bit when you see 3 and slice the 32 bit with parity in something like 8 8 9 bits. LikeLikedUnlike Reply S.Ma (Customer) SpletThe JTAG-to-SWD sequence is at least 50 TCK/SWCLK cycles with TMS/SWDIO high, putting either interface logic into reset state, followed by a specific 16-bit sequence and finally a line reset in case the SWJ-DP was already in SWD mode. Bits are stored (and transmitted) LSB-first. Definition at line 115 of file swd.h.
