For LPC546xx errata Rev 2.2, there is an problem about USB1 high speed device data transfers (3.22 USB.15:USB high-speed device in endpoint TX data corruption). A former post said the work around will be available in SDK. I wonder when the solution will be available.
This link (https://community.nxp.com/t5/LPC-Microcontrollers/LPC546xx-Errata-3-22/m-p/858489#M34185)said the work around will be available in SDK. Is it available now?
