Linux 燒錄方法 (Linux Flash eMMC Method)
使用Flash tool 燒錄鏡像到eMMC (Flash image into eMMC by Flash Tools)
Step0: 檢查SD卡在Linux 環境的代號 (check SD card symbol in Linux system)
Step1: 創造一張可開機的SD 卡 (Create a bootable SD card)
Command :
~$ sudo dd if=2620A1AIM34LIVC0054_iMX8ULP_1G_flash_tool/image/imx-image-full-imx8ulprom2620a1-20230627062759.rootfs.wic of=/dev/sde bs=1M conv=fsync status=progress
Step2: 將可開機的SD 卡插入底板SD卡卡槽(Plug the SD card into Carrier board 's SD card slot)
Step3: 確認開機選擇指撥開關
| EMMC boot: | SW1301: 1_2_5_6 ON SW1302: 4_6 ON |
| SD boot: | SW1301: 1_2_3_4 ON SW1302: 4_6 ON |
| Serial download: | SW1301: All OFF SW1302: 5_6 ON |
Step4:打開電源 和 終端機 (Turn on the Power & Terminal)
Step5: 複製flash tool到U盤中, 解壓縮flash tools檔案,(copy to USB Disk, then unzip the flash tools file)(Test with 32G SD card)
複製檔案到U盤中 (Copy the flash file to USB Disk), 解壓縮flash tool到home目錄(Unzip the file to home)
- tar zxvf /run/media/New\ Volume-sda/2620A1AIM34LIVC0054_iMX8ULP_1G_flash_tool.tgz -C ~
5. 進入flsah tool下的mk_inand資歷夾, 執行指令./mksd-linux.sh /dev/mmcblk0燒錄image到eMMC(Connect USB Disk to ROM-2620 system, extract the flash tool and browser to mk_inand folder and execute flash shell script "./mksd-linux.sh /dev/mmcblk0"
解壓縮後如果沒有mksd-linux.sh檔案, 可以到以下連結下載並複製到mk_inand資料夾下(If there is no mksd-linux.sh file in mk_inand directory. Please download from the link below and place it in mk_inand directory:
| ROM-2620 | Device node |
| SD card | /dev/mmcblk2 |
| eMMC | /dev/mmcblk0 |
6. 切換開機switch來設定成從eMMC開機(Change boot switch to boot from eMMC. Reboot system).
Debug 串口調試 (Debug port Setting)
以 Tera Term 为例介绍如何使用串口调试功能
Baud Rate波特率：115200 Data 数据位：8 Parity 奇偶校验：无 Stop 停止位：1 Flow Control流控：无
Tera Term Tool
Check the Sriel port in Device Manager (查看PC端的串口号)：
if you can not identify the Serial device , please check your serial driver.
Debug port connection (串口連接)
Log into Terminal Tool (进入串口调试终端)：
Linux系统的基本使用(Linux System Basic Operating Method)
UUU 使用方法(USB Connection (OTG port))
Connect USB cable to USB OTG port.
Change boot switch to "SW1301 all OFF, SW1302: 5_6:on" to boot from force recovery mode.
| Serial download: | SW1301: All OFF SW1302: 5_6 ON |

M33 Function
We use default M-core firmware to verify each of IO feature. User should connect COME_DEBUG port to PC and there were show screen as demonstration below:
Press C for test mode of CAN bus
Press Q for test mode of QSPI
Press M for test mode of LPSPI master
Press S for test mode of LPSPI slave
Press U for test mode of LPUART
About this firmware, user should note that if you want to switch to another test mode, you must reboot the system.
CAN Bus
Step 1: Prepare two pcs rom-2620. One for ‘Node A’ one for ‘Node B’
Step 2: Connect these two boards (HI-HI/LO-LO)
Step 3: The test steps and screen are as below :
Step 4: Follow the figure (step1 - step4). If B node received data means test successful.
QSPI
Step 1: After select the test mode ‘Q’ to verify QSPI, you will see below screen.
Step 2: This test program will perform QSPI erase/write automatically and show ‘successfully’ when it’s done.
Step 3: User can press any key to run again.
LPSPI
Step 1: Two pcs rom-2620. One for ‘Master’ one for ‘Slave’.
Step 2: Connection with these two boards by SPI Bus as below:
LPSPI3_PCS0 -- LPSPI3_PCS0
LPSPI3_GND -- LPSPI3_GND
LPSPI3_PCS1 -- LPSPI3_PCS1
LPSPI3_SCK -- LPSPI3_SCK
LPSPI3_SOUT -- LPSPI3_SIN
LPSPI3_SIN -- LPSPI3_SOUT
Step 3: One board select mode ‘M’ to be Master.
Step 4: The second board is specified to Slave by select mode ‘S’.
Step 5: The test screen as below:
Step 6: Press any key at terminal of node master, it will execute the test again.
LPUART
Step 1: Change ROM-ED91 SW1203 to '01'.
Step 2: Connect COM-B and COM-E to PC.
Step 3: Set RTS/CTS flow control for COM-B in Putty.exe
Step 4: After select the test mode ‘U’ to verify LPUART2, you will see below screen.
Step 5: If tester can input any characters/strings and show that at COM-B means test successful.
