STM32L162RE EEprom programming using STLink utility

I have been working with STM32L162RE MCU. For programming I am using STM32 ST-Link Utility as well as ST-LINK_CLI. From the data sheets I understand that it supports 16KB of Data Eeprom and 512KB of flash memory. I  am able to use 256KB flash in both the banks without any issues. But when I try to program the EE prom using link uitlity, it gives error when I try to program beyond 6KB in bank 2.

I would like to know about  the base address of both the data memory banks. And also need to know how to program the complete 16 KB of data memory available. Any help in this regard is highly appreciated.

Hi r.sivaprasad,

Please refer to 

http://www.st.com/st-web-ui/static/active/en/resource/technical/document/reference_manual/CD00240193.pdf

 to know about the base addresses of the banks.What kind of error do you get when trying to program beyond 6Kb in Bank2? Please share the error message.You shouldn't have an issue as STM32L162RE is CAT5 and you have 8Kb in each bank (referring to table 11 of the reference manual).-Mayla-

Thank you Mayla for your reply.

I am getting an error pop up saying ''Error occurred during memory writing''.Writing to any address 0x08083001-0x08083FFF throws the same error.Also the EEprom information is displayed as 6KB. I am attaching the screenshots for your reference. ________________ Attachments : Data_EEprom_bank.png : https://st--c.eu10.content.force.com/sfc/dist/version/download/?oid=00Db0000000YtG6&ids=0680X000006I0AZ&d=%2Fa%2F0X0000000bcQ%2FMcsNymggutaXNRLYrgcpInat2SXphCBDN5LbI3n5Tw0&asPdf=falseError_Screenshot.png : https://st--c.eu10.content.force.com/sfc/dist/version/download/?oid=00Db0000000YtG6&ids=0680X000006I07v&d=%2Fa%2F0X0000000bcO%2FDWeOelYw0MJl9Ogbd6.bqpwiwOiNvtCZFYNS5jF1s7Q&asPdf=false

Suggest you validate the EEPROM functionlity from your own code

Yes.. It works fine writing the EEPROM from the code.. I suspect the issue is with STM Link Utility/CLI  application. Please advise

ST-LINK V3.9.0 was released the other day.

Really not much I can do to elevate this issue, or remediate it. I suspect you will need to solve the problem using a different approach.Suggest you push into ST via sales/distribution channels.

I wouldn't write to odd addresses, and would probably shrink the write length to it doesn't exceed capacity.I will push to moderation again.
