KE06 Unsecure flash command

albert4 — Sat, 05 Jun 2021 15:20:04 GMT

JFlash failed to download code to KE06 Flash, causing Flash to be in secure mode.Is there any way for Flash to exit secure mode?Please provide detailed steps to solve the problem。

If KE06's Flash is secure, the JLink emulator cannot emulate the code.

Chip erase not supported for flash bank @ 0x00000000. Switched to sector erase

Hi albert,

Please try this command "unlock kinetis" in Segger J-LINK commander.

You can refer to this document for kinetis lock issue.
