which chipset? there are known problems with profilic-chips
probaly profilic and i dosent matter if i press </> it still looks like in previus post
the lede image is 907 maby i have the vrong one
Maby i have connected it wrong on the db9 plug
db9? an old COM-Port? attention, this may have 12V!
it is a usb to db9 serial adapter
can you turn off flow-control in putty?
hi Frank
yes i have tryed that also
your usb2serial has clean state in device-manager?? ok, else you should got nothing…i needed some time to get working driver for my cp2102, but now it works as expected
bpi-r2-serial.reg (14,2 KB)
you have to change com-port to yours
hi Frank
but how did you get to the uboot promt so run the emmc pconf 48
kenn
is it now working?
on booting you see the uboot-menu in debug-uart:
here you can see it: http://www.fw-web.de/dokuwiki/doku.php?id=en:bpi-r2:uboot
there take the last menu-item “U-Boot console”
Hi Frank
How do you make the uboot image to put on the sd card do you have a image or
kenn
why not scrolling that wiki-page a bit down to #update_uboot 
you find compiled actual uboot (with emmc) on my gdrive: https://drive.google.com/drive/folders/15Y5Y3NAOwg_IMmN3k6hdb7pAQj9oTVTl
Hi frank
i can see the uboot menu in my console but hov do you stop it from continuing booting from sd it goes past fast and i can only find it by scrolling back
pressing any key (e.g. cursor down to move inside menu) while it is displayed (for about ~3 seconds)
connect first uart and than boot…or reboot after connecting uart if system already running
Hi Frank
still no luck i have ordred the cp2102 hope that helps it still just boots no matter what key i press i have installed the reg key with my com port but no luck is it not possibel to make a uboot image that boots strait into uboot promt seems very dificult to use that emmc
kenn
back to Bluetooth…does anybody got a working connection? which tools are used which commands. please post log of init and connection.
