REL Q3'17 - Bootloader updates v0244

Scope

The DAPLink team has created a bootloader update process so older bootloaders can be replaced. This allows users who are experiencing bootloader problems (e.g. older boards using CMSIS-DAP bootloader with Windows 10) to replace their bootloader with a new version (latest DAPLink bootloader) which does not have these problems. This is a public release intended for a one time bootloader update. See the mbed blog post for steps to apply this update.

Bootloader Update Builds

• 0244_k20dx_bootloader_update_0x5000.bin
• 0244_k20dx_bootloader_update_0x8000.bin
• 0244_sam3u2c_bootloader_update_0x5000.bin
• 0244_sam3u2c_bootloader_update_0x8000.bin

Bootloader features removed for the 0x5000 build

• Hex file support
• Info files MBED.HTM, ASSERT.TXT, NEED_BL.TXT
• Entries from details.txt
• All action commands aside from REFRESH.ACT and START_IF.ACT
• All error messages in FAIL.TXT except for success and failure

Bootloader features removed for the 0x8000 build

No bootloader features were removed for the 0x8000 build.

Issues

• No known issues that this time
