EC3 debugger cannot read SL51 flash
The adapter is connected and detected properly using ec2adapters
. Reading the adapter's firmware also works, but not reading the microcontroller's flash contents.
Microcontroller: C8051F330 Adapter: USB Debug Adapter, EC3 debugger
Host OS: Ubuntu 18.04 Compiler: GCC 7.3
Code modifications: ec2drv.c
: #define HAVE_USB_DETACH_KERNEL_DRIVER_NP 1
(Spoiler) Flash reading with debug output enabled
$ sudo ./ec2readflash --port=USB --mode=C2 --debug
