Useful for your situation are chapter 8.2 and 8.3.</P><P>Also Chapter 4 Board recovery from <A href="https://community.nxp.com/legacyfs/online/269233_AN5184_Programing_SD_MMC_ARMv7.pdf">https://community.nxp.com/servlet/JiveServlet/downloadBody/332382-102-2-269233/AN5184_Programing_SD_MMC_ARMv7.pdf</A>, provides the necessary steps for board recovery.</P></BODY></HTML> Thu, 29 Nov 2018 06:39:03 GMT https://community.nxp.com/t5/QorIQ/Codewarrior-TAP-Suddenly-Failing-to-Connect/m-p/813695#M6888 ufedor 2018-11-29T06:39:03Z
