I have a custom design prototype that I'd like to flash. No luck so far.
This board has a 2Gb (256Mo) LPDDR4 DRAM with a single 16bit width bus. I've tried to generate a DCD file to configure DRAM correctly.
The device is connected via USB and I can see it in dmesg (idVendor=1fc9, idProduct=0134). When flashing my binary onto it, uuu seems to do the job correctly. Then the USB device gets disconnected and reconnected rather than going to the next boot step (i.e. SDPU/SDPV). It looks like the device is reset and I think it has to do with the DRAM not being properly initialized.
Where can I find a DCD configuration file example close enough to my configuration? How can I generate the proper DCD file?
