Unielec 7621-06 serial speed please set to 57600

Hi all, I hope developers are here?

Please change console speed for Unielec 7621-06 from 115200 to 57600 (via mt7621_unielec_u7621-06.dtsi).

57600 is uboot speed, so if openwrt change during boot to 115200, communication is left.

I also have UniElec 7621-06 (256M/16M) but the board is using Breed as bootloader, not uboot.

When did you buy it? I bought mine at march 2020:

U-Boot 1.1.3 (Dec 24 2014 - 22:25:27)

Board: Ralink APSoC DRAM:  512 MB

find flash: MX66L51235F
*** Warning - bad CRC, using default environment

Ralink UBoot Version:
ASIC 7621_MP (MAC to MT7530 Mode)
DRAM_CONF_FROM: Auto-Detection
DRAM bus: 16 bit

 ##### The CPU freq = 880 MHZ ####
 estimate memory size =512 Mbytes

Please choose the operation:
   1: Load system code to SDRAM via TFTP.
   2: Load system code then write to Flash via TFTP.
   3: Boot system code via Flash (default).
   4: Entr boot command line interface.
   7: Load Boot Loader code then write to Flash via Serial.
   9: Load Boot Loader code then write to Flash via TFTP.                                                                             0

3: System Boot system code via Flash.

I bought mine in 2018, and it has Breed bootloader preinstalled. The Breed Web Recovery Console webpage says the version is "1.0 (r777)" and compiled on 2015-10-18 [git-bb5218f]. I can't find the corresponding version for the board here though. I would be grateful if @hackpascal can update it to the latest version.

Note: Your device is 512M RAM / 64M Flash, while my device is 256M RAM / 16M Flash.

By the way, does anyone know how to compile U-Boot for this board? I find this repo which appears to be U-Boot for MT7621...

What a problem? Insructions looks quite clear. I just compiled it. But did not install to router :slight_smile:

I didnt found profiles for Unielec. Also only for you here the list of settings from menuconfig:

Cross Compiler Path: "/opt/mips-2012.03/bin" 
 (115200) UART baudrate 
 (MT7621) Chip ID 
 (GMAC1) Use GE1 or GE2 
 (GE_RGMII_FORCE_1000) GE1 connected to 
 (SPI) Flash Type 
 [*] Use 50MHz SPI clock 
 (500Mhz) CPU Frequency 
 (1024Mb) DDR Component 
 (1066Mhz) DRAM Speed 
 [*] Dual Core Support 
 [ ] DDR ACTiming Setting 
 (RAM) Ram/Rom version 
 [ ] USB Recovery 
 [ ] Partition LAN/WAN 
 [*] Enable all Ethernet PHY 
 --- GPIO pins (-1 mean unused) 
 (41) BTN Reset GPIO 
 (-1) BTN Misc #1 GPIO 
 (-1) BTN Misc #2 GPIO 
 [ ] LED Pins Inverted 
 (-1) LED All GPIO 
 (13) LED Init1 GPIO 
 (44) LED Init2 GPIO

 (-1) LED Init4 GPIO 
 (-1) LED Init5 GPIO

 (47) LED Alert1 GPIO

 (-1) LED Alert4 GPIO 
 (48) LED Power GPIO 
 (-1) USB #1 5V Power GPIO 
 (-1) USB #2 5V Power GPIO 
 (-1) Reset iNIC GPIO

Absolutely not clear which setting should be for Unielec.

p.s. it looks like the http://www.denx.de/wiki/U-Boot/WebHome is more suitable to use. But I cannot find there mt7621 support :frowning:
