BL602 SDV-002_V1.2 Flashing Fails: UART Shows Boot, Bouffalo Lab Cant Read Flash ID

Question

BL602 Module SDV-002_V1.2 unable to flash I have this product With Bouffalo Lab I can't read flash id as described here: but i have this logs on UART AI: Can you specify which Bouffalo Lab tool (and version) you are using to flash the BL602, and whether you’re using the command line or GUI?...

insmod · Answer

SDV-002_V1.2 is problematic because the boot pin is not available unless you unsolder the module. How to do it without unsoldering: BK7231GUIFlashTool can be used for flashing.
