Garbage in UART output on uboot (not Openwrt)
Posted: Thu May 18, 2023 1:26 pm
Hello,
I've been using lots of Vocore2 boards without problem for years, but since my last two purcharses, the new boards failed to show properly the u-boot stage in serial console. The same three Vocore2 boards but purcharsed 2 years ago worked fine with the same setup. This makes me unable to flash a new firmware via kermit, for example.
In all cases when uboot gives the control to OpenWRT, UART console is working and I'm able to operate normally. I've cheched this in Linux and Windows (Putty). Settings are typical 115200 8N1 No flow control.
I've testes with other baudrates, lower and higher, with no success.
Anyone else with this problem?
