I am using just the LPC Link side of a LPC1115 Lpcxpresso board, trying to program via SWD a LPC11E37 target, in custom hardware.
The default programming speed is too high for my setup (there are couplers on the path) and by analyzing SWD protocol, I see that the ACK is not transmitted well because of clock delay.
Is it possible to adapt LPCLink's SWD speed through their LPCxpresso IDE?
If not, what similar programmer would do the job in lower rate? E.g. LPC-Link2?
Thank you for the support

Link and Link2 doesn't allow to change speed.

See: Reducing wire speed

Note : This above wire speed information only relates to connections using RedProbe(+). LPC-Link only supports fixed wire speeds.
