[QUOTE="slugworth, post: 97857, member: 177380"] Sti5518 jtag pinouts for receivers not having a 20pin jtag connector. Add 100 ohm resistors inline with the signal lines between sti5518 and the db25. DB25 pin2--------->TMS 110 \ DB25 pin3--------->TCK 113 \ DB25 pin4--------->TDI 112 --on Sti5518 processor DB25 pin5--------->TRST 109 / DB25 pin13-------->TDO 111 / DB25 pin25-------->GND The JTAG pinouts for STi5518 are as follows: TRST: pin109 TMS : pin110 TDO : pin111 TDI : pin112 TCK : pin113 BFR : pin115 "ground this pin @ receiver ac powerup to put processor into BFR mode".This will allow erase/writes of the tsop with jkeys.
