Has anyone used the Ulink USB-JTAG adaptor to target a Philips LPC2214 that is in a JTAG chain with an Altera FPGA, e.g. cyclone? The manual chain configuration allows one to enter the Altera IDCODE and IR length etc. as well as the Philips IDCODE and IR lengthh etc. The Settings view then shows two devices - and the Philips "radio" button is selected to indicate the device the debugger should "talk" to. However, a simple verify fails repeatedly with "ARM cannot be reset; Check JTAG cable" or similar. My chain setup is as follows: ULINK TDI--> Altera TDI --> Altera TDO --> LPC TDI --> LPC TDO --> ULINK TDO. TMS and TCK are parallel to both. If I physically isolate the Altera from the TDI/TDO chain (isolate Altera and Short ULINK TDI to LPC TDI) such that there is only the LPC in the chain, all is well. Any experience/ comment welcomed. Thanks Wayne
Currently there is a problem with JTAG chaining. However we will address this issue in the next weeks. Reinhard
