Hello ,
I am try to build Thermal Printer using TM4C1233H6PM controller with TI's application note and firmware.
The Thermal Head used in my schematics is LTP02-245 from Sekio
I have assembled the board and powered up and connected with usb . Then , in system it is showing "Stellaries Firmware Upgrade" and I programmed with the firmware given in application note named "THERMAL PRINTER 4F PORTED_V6.out" with uniflash 3.1.0 utility.And shows successfully programmed.
But after programming ,the controller is not at all detecting through usb . And I don't have any jtag programmers with me for checking . Secondly the flashed program also not working ,I tried with application program "TIVA-
THERMAL PRINTER DEMO INTERFACE" .in that it is not detecting with serial port .
Please help me for solving the issue.
Schematics attached for reference.
