How did you update bootloader from 1.65 to 1.70? Is it possible to revise it back to confirm if the problem was caused by different bootloader version?</DIV> <DIV>2.&nbsp; I didn't see any existing report for bootloader 1.70. So to position the issue, please do some test:</DIV> <DIV>- test it with a simple demo code, for example, toggle a led. Is it work normal on both 1.65 and 1.70?</DIV> <DIV>- test system clock. Are both of them the same system clock?</DIV> <DIV>- which module can't work normal on 1.70?</DIV> <DIV>&nbsp;</DIV> <DIV>Have a nice day</DIV> <DIV>Jun Zhang</DIV> </DIV> Fri, 23 Apr 2021 01:57:53 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC2129FBD64-Bootloader-version-1-65-to-1-70/m-p/1266957#M44750 ZhangJennie 2021-04-23T01:57:53Z
