We are currently working with a new STM32F4 chip with the following internal flash and Ram address:
iROM - Starting address: 0x00000000, Size = 1M bytes
iRAM - Starting address: 0x20000000, Size = 128K bytes
So far we have not been able to transfer program into the internal flash of this new STM32F4 device. We have tested on IAR EWM, KEIL uVison 5 as well as Coocox IDE and none of them work. We are able to debug the program when the program code is loaded into RAM but not when we select the program to be stored into the embedded flash. When we attempted to debug program in flash in KEIL uVison 5 the log windows said "No algorithm for address xxxx".
We checked all the existing STM32F4 devices and their iROM always start at 0x80000000. This new device seems to be the only STM32F4 where the iROM starts from 0x00000000. Does J-Link need a special algorithm to handle flash programming of a STM32F4 device that is starting at address 0x00000000? If so how can we obtain the algorithm?
Thank you in advance for any help.
