I am using the PG-FP6 to make this IC programming,it can be read signature and programming ,verify etc.but after program and verify pass,then I try to do blank check,it is still pass.So that it is not programming anything inside.
it is strange.
Can you kindly give your help about this issue?
Program-verify and blank check are 2 different sessions. Between these 2 sessions PG-FP6 is disconnected from RX23T and power supply to RX23T is switched off. The code, that is programmed to RX23T, does not have an ID code programmed. When PG-FP6 connects to a device, the device checks if an ID check is necessary. If no ID code is programmed the boot loader by default erases all on-chip flash. Please see figure 34.19 from RX23T hardware user's manual. So blank check is successfull.
