Ok, trying again the ISP mode worked! Now I'm connected. Probably I made a mistake in the previous trials. Problem fixed! Thank you for the support! |
Hi, unfortunately still no way to access the lpc4357 through the Link2. To summarize, there's a list of things I tried. - I've installed now LPCXpresso 7.8.0 - I'm using "non-bridged" version of CMSIS-DAP (see picture) - LPC-Link2 attached to a USB2 port (I also tried an external usb hub between the USB2 port and the link2, without success) - EA-LPC4357 board powered externally with 5Volt source. - I've tried to put lpc4357 into USART0 ISP mode, putting P2_9=P2_8=P1_2=P1_1=LOW at boot, while P2_7 is pulled down during reset. - I've also used a second PC, still with Windows 8 and LPCXpresso 7.8.0, but without success. - I can see activity on the oscilloscope of the JTAG. Considering I can see the activity on the JTAG I may suspect the issue is in the LPC4357 "locked"..is it correct? - No Redlink processes in Task Manager - I've tried 2link2 programmers and 2 EA-LPC4357 boards. The problem is in both harware kits. The problem now is : RedlinkAPI: Wire Ack Fault. target connected? Any other suggestions?
