https://community.nxp.com/t5/MCUXpresso-General/GUI-Flash-Tool-and-LPC-Link2-max-clock/m-p/1281245#M4166 <P>I am using the GUI Flash Tool on MCUXpresso 11.3.0 with LPC Link2 board to update spifi flash on a board with LPC54S018J4M MCU. The MCU board has a 6-pin SWD connection. The tag connect cable from <A href="https://www.tag-connect.com/product/tc2030-ctx-6-pin-cable-for-arm-cortex" target="_blank">https://www.tag-connect.com/product/tc2030-ctx-6-pin-cable-for-arm-cortex</A> connects the LPC Link2 board to the MCU board.</P><P>I had trouble erasing or writing to the spifi flash in the MCU until I changed the wire speed to 100000. What is the max clock rate supported by LPC Link2? I didn't need to set the wire speed before. Not sure when this started happening. Can anyone provide some information to explain why this happened?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="rex_lam_0-1621878168683.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/145387iA4B4D0D4B97CA8C3/image-size/medium?v=v2&amp;px=400" role="button" title="rex_lam_0-1621878168683.png" alt="rex_lam_0-1621878168683.png" /></span></P><P>&nbsp;</P> Mon, 24 May 2021 17:44:15 GMT rex_lam 2021-05-24T17:44:15Z https://community.nxp.com/t5/MCUXpresso-General/GUI-Flash-Tool-and-LPC-Link2-max-clock/m-p/1281245#M4166 <P>I am using the GUI Flash Tool on MCUXpresso 11.3.0 with LPC Link2 board to update spifi flash on a board with LPC54S018J4M MCU.
