I have a TSW1400EVM that I am using to evaluate the tsw1266. When I attempt to download firmware I receive the following warning.Text reads: "Download Firmware JTAG_CHAIN_BROKEN_ERROR The JTAG chain was broken while loading firmware". I search the forum and find someone others has the same error.( » » » » » » ).
I confirm my board has R55 installed.Ken.C said that removing R55 (the 1k pull down on FPGA_TCK) fixed the problem.I want to kown whether you confirm it.If removing R55 can fix it,i will remove R55 myself.
