After making a prototype based on SAML21 board (SAML21J18B/WLCSP) I've encoutered a problem trying to program its flash (via SWD protocol using atmel-ice debugger).
I've been able to erase, but when I try actually programming it I receive the following message :
Programming starts at address 0x0 and even after changing that address I keep having the same error message ( which seems to mean that I can't write anywhere on the flash ).
Code: Select all
Severity: ERROR ComponentId: 20100 StatusCode: 131103 ModuleName: TCF command: Modules:writeToMemory failed. Failed to write segment at 0x0 to target for memorytype base
I hope that some of you have some insight ( or any hint really ) on this type of issue.
