Hello, I think the problems I posted recently regarding JTAG problems of the LPC2138 mask A and B, are caused by the bootloader. The mask A device has version 2.00 , the mask B device has 2.11 (B works perfectly). How can I change the bootloader in the mask A device ? I didn't find a tool which allows to change the bootloader for the LPC2138. For other members of the LPC21xx family there a

Hi, I'd like to measure the performance of some code I'm using, but this doesn't seem very easy to do with the LPC2138. (using freeRTOS and Rowley). In windows I'd use QueryPerformanceCounter() to get a time stamp before and after. Is there an way to do this with the LPC? Or do I need to set up a timer interrupt every 1?s or something to increment a counter? Thanks.

I am having no luck with the LPC2000 Flash Utility (V2.2.1) and LPC2138 chips I tried with P14 low (although on the LPC2106 this doesn't matter as the ISP runs if there is not a valid program in it) I can see the data going into UART0 but the output remains high impedance.
