Example for writing to FLASH on the cc1110, cc2510 or cc2430

The cpu example without modifying if downloaded to the CC1110 (26MHz Osc).

The FWT = 0x11; which is here observing :

datasheet CC1110 : Page no 88 of 244 : 12.3.5 Flash Write Timing:

FWT = (21000*F)/(16*10⁹) = 21 x 26 / 16 = 0x22. Where F is 26MHz Osc frequency.

but

"The initial value held in FWT.FWT[5:0] after a reset is 0x11, which corresponds to 13 MHz system clock frequency ( calibrated HSRCOSC frequency for CC1110Fx when using a 26 MHz XOSC )."

Makes me confused for 0x11. Neither 0x22 nor 0x11 work here. However It should not be 0x22. Because the Osc frequency is itself 26MHz so the clock can be the half of the Osc frequency at max. Hence 0x11 seems the number.

FWT = (21000*F)/(16*10⁹) = 21 x 13 / 16 = 0x11.

But not working.

What could be the reason?

Dear Firefighter,

Thanks for your answer. As I've mentioned that I did not change the cpu flash code example. Just ran to check its output. I could not find the change in memory section of the IAR IDE. Where to look for change in flash memory in the IDE itself in debug mode?

Or I might be doing something wrong. I want to save some data into a non-volatile memory of CC1110 and retain its values in power cycles. I want to do both read and write. Post which I'll do it with DMA.

Thanks

hello forum,

I am trying to write some data stored in RAM to flash memory using DMA. When ever i initiate the flash write for first time, it works fine and data will be getting written to flash mem. I use CRC mechanism to check the change in RAM data and initiate flash write again if CRC is changed. When CRC is changed i initiate flash write again with the same configuration which fails (no data getting written to flash memory).

can anybody please suggest me what may be the issue?

hello,

Can somebody reply to my question??

thank you.

Hi Rahul,

     I am facing same problem.... did your work, if working then let me what are changes to do.

Thanks
