Hi,

       I am assuming blhost is compatible with the ROM bootloader (according to blhost user guide). According to the document it should work with UART and USB. But for some reason, I cant get it to work (both from Windows and Linux host).

Does it really work with ROM bootloader? Or is it meant to work with the flash resident bootlader? Which interface should I be using? I actually like to get it working with UART if possible.

Windows

It does not show up as a COM port (As per the Rom Bootlader User guide, KBTLDRUG.pdf, I was expecting a CDC COM port ). Only enumerates as  'USB MASS Storage Device.' So left with only one option RS232 on the TWR-SER board.

 

Desktop>blhost -p COM4 -- get-property 1 Error: Initial ping failure: No response received for ping command.

 

Linux

Shows up as usb and ACM device. Yet both did not work.

USB

./blhost -u 0x2504,0x00200 -d get-property 1

Error: UsbHidPeripheral() cannot open USB HID device (vid=0x2504, pid=0x0200, sn=).

 

  UART

TWR RS232

./blhost -p /dev/ttyUSB0 -- get-property 1 Error: Initial ping failure: No response received for ping command

 

Many Thanks,

Tony
