#407 Error by connecting to the target via ICE (tlsr9518fd80d kit)

[Majd Abdullah]

Hello everybody!

I am using Telink RDS program to make a project for the kit (tlsr9518fd80d), and i am using inserted tools (connect the target via ICE) to download the (.bin) code to in the flash.

• The programmer is (tlsr9_dev_key).

Everything was fine and I used it normally for 3 months, but suddenly I got this error:

10:37:25.004 ICE-ICE Error on Target [ADP-AE350-D25F-EAGLE-0106]

I get a new kit and it had worked normally, but after month i get the same error.
And now I have two broken kits.
can somebody help to fix the problem

You might want to attach a verbose (openocd -d3) log.
You should maybe also try a more up to date build of OpenOCD built from the RISC-V fork:

Hi Tommy,

https://github.com/riscv/riscv-openocd i see the last release version is from Dec 2018 (almost 4.5 years old). Do you know if there is any latest release version available or master branch is the most updated one after 2018 that shall be used.

The RISC-V OpenOCD fork is under constant development/refinement.
You really need to build from the latest sources to get the latest updates.
You could try, say, the xPack binary builds but they will still usually lag behind the bleeding edge RISC-V fork repo sources.
