topic How to Make DMA-UART work with KL05 and series? in Kinetis Microcontrollers https://community.nxp.com/t5/Kinetis-Microcontrollers/How-to-Make-DMA-UART-work-with-KL05-and-series/m-p/304246#M12869 <HTML><HEAD></HEAD><BODY><P>Hi</P><P>I am using code warrior 10.5 along with PE , I wanted to test a program in which I will be sending some commands using terminal window to UART0 and it will be received through DMA and will send it back to the terminal(with or without DMA). I have done this for K20 and other K series and it is working fine. But it didn't work with Kl05 and FRDM-Kl46Z here is the attached code . I tried the sample code present in the codewarrior for MKL05Z32VLF4. and also tried the code given in <A _jive_internal="true" href="https://community.nxp.com/external-link.jspa?url=http%3A%2F%2Fcache.freescale.com%2Ffiles%2F32bit%2Fdoc%2Fquick_ref_guide%2FKLQRUG.pdf%3Ffpsp%3D1%26WT_TYPE%3DUsers%2520Guides%26WT_VENDOR%3DFREESCALE%26WT_FILE_FORMAT%3Dpdf%26WT_ASSET%3DDocumentation" rel="nofollow" target="_blank">KLQRG</A>, chapter no 7. even that didn't work.
