CMSIS-DAP: Kinetis Device is locked!
Hi,
I am using the KL46z board with the Keil IDE, CMSIS-DAP, and while working last night my board locked up and refuses to cooperate.
The board can't be programmed by either Keil nor saving the precompiled code onto the device and resetting. However, the board can still go into bootloader mode. While in that mode, I can successfully download the BOOTUPAPP_Pemicro_v111.SDA firmware, but the Application Version remains 0.00. To combat this, I tried downloading the 20140503_k20dx128_kl46z_if_opensda.s19 and it seems to download correctly but the Application Version remains 0.00.
Besides that initial error, I get no other error.
Thank you in advance for your help, Jake
