R8C2 resistor.....Is it necessary?

[MrKronic]

This might be a pretty noob question, but it has been circling my head a lot. Does the R8C2 1k resistor at the alt cpu_rst point have to be replaced in case it gets torn off? I mean, in a JTAG box is there any impact on functionality if the resistor is not there? I've read that the resistor is a debugging header, but nothing much about its significance in r-jtag or glitch hacks. TIA

should run fine from what ive hard by just bridging it.ofc the best recommendation is to replace it though.

yes, but why? Does it affect the reset signal in any way?

anything in between ur cpu rst solder point and the rgh chip point can effect signal,cpu rst is kinda touchy.

Is this is the reason why the glitch cycle is not very consistent?

A resistor on the reset line will have an effect on the reset pulse, naturally.
