    • Jflash - Error connecting to ATSAML11E15A after programming

      Hello.

      I am having a problem reconnecting to ATSAML11E15A after programming using JFlash. We are using JFlash in a factory tool to program 2 different micros. I am using JFlash V6.54 and a JLink Plus Compact. I have been able to successfully connect to and program the L11 but I get an error after disconnecting and re-connecting. I can no longer communicate with the chip. I have to erase the chip using ATMEL-ICE and then I am able to connect again. A have no issues when programming with the ATMEL-ICE but we can't use it in our factory tool architecture to program both micros.

    • Hello Darlene,
      Thank you for your inquiry.
      Such an issue is not known to us.

      Is this reproducible on an evalboard?
      If so, on which?
      Could you provide us with a .hex file to reproduce this issue?

      Best regards,
      Fabian
