There is a iap_18xx_43xx.h which is the right one.</SPAN><BR /><SPAN>2) Please introduce 'uint8_t Chip_IAP_Init (void);' to the iap_18xx_43xx.c/h. This is a necessary function to be called for erasing and writing the flash. It is mentioned in the manual UM10503.pdf, but it's missing in LPCOpen.</SPAN><BR /><SPAN>In UM10503.pdf it is stated, that the Init is giving back a CMD_SUCCESS (which is 0), but I don't observe any given back value. It is also not clear whether this function has to be called once, or every time before writing or erasing functions are called.</SPAN><BR /><SPAN>3) Please change the declaration and definition of iap_entry. In declaration and definition 'unsigned int' is used. But in the calling functions (in iap_18xx_43xx.c the arrays are of type uint32_t. This gives warning messages.</SPAN><BR /><BR /><SPAN>Regards</SPAN><BR /><SPAN> Robert</SPAN></BODY></HTML> Wed, 15 Jun 2016 20:15:35 GMT lpcware 2016-06-15T20:15:35Z LPCOpen 2.16 LPC43xx suggestions https://community.nxp.com/t5/LPC-Microcontrollers/LPCOpen-2-16-LPC43xx-suggestions/m-p/576075#M19363 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by robekras on Thu Apr 09 07:20:00 MST 2015</STRONG><BR /><SPAN>Some suggestions for changes to LPCOpen for LPC43xx</SPAN><BR /><BR /><SPAN>1) Please remove the iap.h.
