crlf crlf

Hi everyone,
Yesterday I upload code on my board(STM32F303k8T6) one time.I use STlink V2 mini SWD programmer(SWDCLK,SWDIO,3.3v, gnd) After I try to upload new code in uc but keil say "device not found" but its connected. After I think keil try to erase code in flash so its get error.I connect nrst pin with rst pin in STlink V2 mini. After keil send error "Could not stop cortex-M device. Please check the JTAG cable". Can someone help me?
Thanks.

    Hi All,
    I have a different environment but the same error message. I've been working on a project for several years with uVision5, ULINKpro D JTAG, and an LPC1833 processor. We have upgraded our product to use the LPC1833 Rev A processor, which fixes some peripheral issues, and when I try to download from uV5 I get the "Could not stop Cortex-M device..." error message. Using J-Flash, we determined that the LPC1833 Rev A chip has a different core id than the LPC1833 and we were able to program the Rev A chip with J-Flash by disabling the core id check.

    Is there a new Device Family Pack that supports the Rev A chip?

    Thanks.
