Hello everyone.
I downloaded the Radxa CM3 RASPCM4IO image to the CM3SODIMM module.
I installed CM3SODIMM on the board where Raspberry Pi CM3 is running and shorted the EMMC_DISABLE_N pin to enter boot mode.
When I uploaded other Radxa CM3 Ubuntu images, there was no problem, but after uploading ‘Radxa CM3 RASPCM4IO’, even if EMMC_DISABLE_N is shorted, it does not enter boot mode.
The LED on the CM3SODIMM is blinking at 1 second intervals.
Does anyone know how to enter bootmode or download an image from this state?
help me…
Thanks for reading.
