Hi,
I think that IAR has not updated their LPC17xx.mac file to work with the latest LPC1758 version, since the following error is raised :
C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.4\arm/config/flashloader/NXP/LPC17xx.mac(40,17): Error: Operation error.
However I’m not sure what needs to be changed to make it work.
Can anyone help me with this?
