Switch from LPC2136 to LPC2138

Development Boards MicroMod
1

Hello everybody :smiley:

I’ve a quick question regarding WinARM tool chain (4.0.2) :

I’m working with a development hardware board based on LPC2138 and the code runs properly. We ask me to get it working on a LPC2136, but the MCU seems to reboot (reset) every time with the same code (the hardware is same) :shock: :?

I think this is due to a bad config of the linker or bad vectors mapping :

  • in the makefile : I’ve changed only ‘SUBMDL = LPC2138’ to ‘SUBMDL = LPC2136’

  • in the linker file (lpc2136-ROM.ld) : same file as lpc2138-ROM.ld but I’ve change only the ROM lengh (‘512k’ to ‘256k’).

  • in the LPC2000 bootloader : change LPC2138 to LPC2136 for the target.

Do you see other changes to switch from LPC2138 to LPC2136 MCU ?

Any idea about the MCU reset ?

Thanks in advance for your help :slight_smile:

Regards,

David
