I have a TLC5943 EVM (2 actually), that when powered up seems to be functional (no smoke, and the LEDs are driven in a very colorful 'scrolling rainbow' scheme).
When I start up the GUI from my Windows-XP computer, it finds the EVM (USB connected) and within a few seconds pops up a window that says the EVM 'DSP firmware update', The board does not have firmware. The wizard will update the Flash on the DSP board... click next step'.
I follow the on-screen instructions for re-flashing the unit. Re-boot the EVM, only to get the same error message. I have rebooted the entire PC, and EVM to no avail.
The DSP board has a hand-written number of "28190 400"
Any suggestions as to getting around this flaw?
