Information in this article applies to:
I am using the Ethernet controller on the LPC23xx devices (A-Step version). After initalization of the Ethernet software I am getting the following error from ULINK:
ULINK - ARM Error: Could not stop ARM device! Please check the JTAG cable.
What can be wrong?
The A-Step devices require a slightly different Ethernet initialization (explained also in the NXP errata sheet). It is required that you change the initalization code as explained in the Knowledgebase Article MCB2300: ETHERNET INTERFACE FAILS ON A-STEP DEVICES
