Below command can switch rockusb loader mode into maskrom mode: rkdeveloptool rd 3
I think the loader you are using, has turn off the read back function to prevent the firmware leakage, all the read returns 'cc'. The gpt is actually write correctly...
I'm sorry that RK3188 is not support in kernel 4.4, please try to use mainline kernel if you want to try with new kernel.
Maybe you should decode the endpoint info from device configuration instead of hard code for it.
All RK3399 share the same rockusb ID, which is 2207:330C, and rkdeveloptool only work correct with this ID on RK3399,
support for internal phy is WIP, current U-Boot only support external phy.
please share the log when you report issue.
The key point is below log, make sure sure you have the correct dts. "Can't find alias serial2 No serial driver found" And the mainline U-Boot has support this board...
We never meet similar issue, did you change any boot code? pls try to print the address of gd->bd->bi_dram[0].start.
What issue do you met?
