Uploading Sketch to Maple mini from Arduino 1.6.9 [SOLVED]

Hello there!
I’ve one of those maple mini clones. I put this new boot loader “maple_mini_boot20.bin” using FTDI 232 interface. I then connected the maple via usb and tried uploading sketch from Arduino 1.6.9 IDE. It failed and gave errors as below..
Sketch uses 12,284 bytes (9%) of program storage space. Maximum is 122,880 bytes.
Global variables use 2,560 bytes of dynamic memory.

Oh, in that case, I’ve encountered that exact symptom before.

Try tweaking the delay in the maple_upload script in the Arduino_STM32 directory under tools/linux or tools/linux64. On my laptop, a 1000ms delay works consistently, whereas the default of 750ms never worked.

Thanks a lot, Devan!!

1500 ms works fine with my desktop pc. I can now upload the sketch with ease. Case closed!
