Getting "invalid Intel HEX file (Invalid line start character (60))" when trying to flash

[sanderalewijnse]

Hi helpful people,

I was trying to flash my cube with your firmware under ledcube8x8x8/firmware/v2/ledcube8.hex using stcgal on my linux machine.

I ran:
stcgal -P stc12 <path_to>/ledcube8.hex

The output I got:
Waiting for MCU, please cycle power: done
Protocol detected: stc12
Target model:
Name: STC12C5A60S2
Magic: D17E
Code flash: 60.0 KB
EEPROM flash: 2.0 KB
Target frequency: 23.962 MHz
Target BSL version: 7.1I
Target options:
reset_pin_enabled=True
low_voltage_reset=False
oscillator_stable_delay=32768
por_reset_delay=long
clock_gain=high
clock_source=external
watchdog_por_enabled=False
watchdog_stop_idle=True
watchdog_prescale=256
eeprom_erase_enabled=False
bsl_pindetect_enabled=False
Loading flash: I/O error: invalid Intel HEX file (Invalid line start character (60))
Disconnected!

Any idea what could be causing this? Thank you!
