CC2540 flash space

Hi,

CC2540 comes with 128 or 256 KB flash sizes. You will also find the information in the CC2540 datasheet:

Hi,

So I want to store my data,

is not the biggest can go to 512k of flash memory(CC2540)?

Best Regrads

thanks

Hi,

if you need more than 256 KB flash size, then you will need to have an external flash device (e.g. a flash module with SPI interface)

Hello,

I have a question about flash controller,

My code is as follows:

---------------------------------------------------------------------------------------------

-  uint8 data1[]={0x61,0x62,0x63,0x64}; 

-  while(FCTL&0x80); //   make sure that erase operation is completed

-  HalFlashWrite(0x3B5D, data1, 1); //actual addr = 0xED74 

---------------------------------------------------------------------------------------------

I entered debug window memory (Xdata) 

It stands to reason I should write to the address in 0xED74 - 0x ED77

Although I see the XDATA memory window  have to change, but the data is not correct

Sometimes will write the memory address is correct, such as 0xFFF0 address

Confirmed XDATA, confirm that there is a successful write

Do not know why

You can help me confused?

In addition, flash write address only provide  0x8000 - 0xFFFF this address? Information written to the flash storage space is only store 32kb  (not external flash)??

Thanks.

Sorry

Who can help me solve this problem??
