FM4 S6E2C2 2048k FLASH + 40k ?

stdec_1820326 Jan 20, 2017 4:31 AM

Hello,

On our S6E2C2, there is 2048k main flash. We can write/erase to that sectors (0x000000 - 0x200000) without a problem. However in the datasheet from Spansion, there is still 40k of flash memory @0x406000 - 0x410000. We can write only to the first sector of 8k. But we can't erase it anymore. Is there a problem with these sectors? Any kind of declaration would be appreciated.

kinds regards

Steven

Hi Steven ,

Please note that  the flash memory of the S6E2C series consists of two macros (called as Macro #0 and #1 in S6E2Cx Flash Programming Guide).

Please refer to Pg No 11 of the flash programming manual

http://www.cypress.com/file/252581/download

The first sector of the 40k of flash memory belongs to the Macro #0 and remaining 32k to the Macro #1.

For all of the sectors in the flash memory (both of Macro #0 and #1), it is necessary to issue the erase command to each Macro #0 and #1.

What is the development tool you are using?
Which erase command was used, flash erase command or sector erase command?

Hello, I am indeed aware that those sectors belong to 2 macro's. But my problem is that I cannot erase SA3#0 ? I'm using eclipse IDE with IAR workbench plugin. I'm using sector erase command. I can share the code for that if you like but I'm not having troubles in the 2k flash range for erasing sectors, and I don't see any difference why that 0x40.. range is different.

kind regards
