LPC-Link2 speed?

danielholala — Thu, 05 Aug 2021 13:59:31 GMT

Hello,

I'd like to know the speed of the LPC-Link2 debug probe but could not find any information about it.

Especially, what is

download speed into RAM
max. target interface speed
max. SWO speed

Segger provides a nice chart providing this information for the J-Link probes here.

Gathering this information facilitates comparison of different probes.

Thanks.
Dan

Hello danielholala,

After confirm with internal, share the below information:

LPCLink2 use HS USB, and maximum SWD speed is about 4MHz

download speed into RAM: ~50KB/s
max. target interface speed: you mean SWD clock speed? ~4MHz.
SWO speed: ~4Mh

Hope it helps,

Alice

Given that on many devices you can get flash programming speeds way in excess of the speed you quote for writing to RAM, I suspect your figures are somewhat out!
