Uther, thanks a lot for the detailed info.Ī lot of progress was already made by you! With the following config green led flashes 7 times (kernel not found according to: … c_pattern)Īnd with this one, green led does not flash at all:
Camtaf - check your download speeds with different machine, check different download files on the same machine, and repeat it with different internet service provider. Hopefully we will know in a couple of days.Īnd just for confirmation, I didn't have any problems with downloading build image and kernel. So for my understanding, the hardware is fine, we're just missing something that might be revealed with serial debugger. After plugin power, the green led is blinking with a distinctive and consistent pattern. It's working properly, and the results are consistent - that's for the good news.īut, after downloading your recent build and applying: I've flashed newest bootloader and double checked it with Raspbian image, ) maybe I will release a new Image If I find evidences of what is missing. We need at least, has additions, in 'config.txt':
I updated the share with newer kernels, from linux-mainline to 5.5-rc7( with last week developments. So 'config.txt', will need one more thing at least. There are also the fact that its not possible yet to use the 4GB Ram, due to the fact that only the 1st 1GB RAM is dma capable. Nevertheless, could be that the developing of it changes the way things were working. ), but here we are also only using sd-card, anyway. Indeed, I also read about it, the bootloader is been updated because it was very basic, with only sd-card support( at beginning. The boot-loader is loaded from flash, as soon ad the processor starts to initialise on boot( what previously was known as ' bootcode.bin'. ) and can help.įor what I read, the booting process of raspberry pi4 is a lot different from the older versions. Maybe someone could have a usb-serial adapter( plus rpi4. can you copy the bootcode.bin to /boot and test?ĮDIT2: bootcode.bin was put in the share, the idea is copying it to /boot on the beta image sdcard.Īny person that has a RaspberryPi4, would be nice to helping us out. I deleted it because I though that all RPi4 come with flash bootcode.bin. That flash holds the bootcode.bin binary usually found in /boot. RPi4 have a small flash that is used to boot usually. Then apply power, to rpi4, and please, post the uart log.ĮDIT1: does you have the last bootloader firmware? ~# cat /dev/your_tty_USB_Serial_converter ~# stty -F /dev/your_tty_USB_Serial_converter 115200 To configure the device as root in yout computer: Also can you attach a serial debugger if you have one, serial to usb converter, and check the output?
