IC-7300 Firmware Version 1.41 固件

下载类型	固件
型号名称	IC-7300
版本	版本 1.41
更新	2021/07/09
主要变化	1.40 版的变化 – 增加了设置项以检测传输过程中的麦克风 PTT 操作，而不是麦克风 PTT 操作。 – 在频谱示波器屏幕的中心模式下，REF 电平设置不反映传输过程中的示波器波形。 – 此固件更新版本 1.41 已得到改进，因此不会重置设置和记忆。如果固件是从 1.40 或更早版本更新的，则不会重置设置和内存。但是，如果固件从更高版本（1.41 之后）恢复到 1.41，设置和记忆可能会被重置。
笔记	更新固件 1. 下载并解压固件数据（例如 7300_141.dat）并将其复制到 SD 卡上的“IC-7300”文件夹中。 2. 将带有固件数据的 SD 卡插入对讲机。 3. 如果您从 1.30 或更早版本更新固件，对讲机将不会显示建议保存步骤 4-4 中描述的设置和内存的对话框，因此我们建议将它们备份到 SD 卡上，以防设置和记忆被重置。 – 如果您从 1.40 或更高版本更新固件，请继续执行步骤 4。 3-1。在菜单中显示 SD CARD 屏幕。 3-2。触摸 SD 卡屏幕上的“保存设置”以打开保存设置屏幕。 3-3。触摸 <<New File>> 以显示 FILE NAME 屏幕。 3-4。触摸 [ENT]，然后出现“保存文件？”对话框。显示，触摸 [YES]。 4. 更新固件。 4-1。在菜单中显示 SD CARD 屏幕。 4-2。触摸 SD 卡屏幕上的“固件更新”以打开固件更新屏幕。 4-3。触摸[▼]滚动到屏幕末尾阅读所有注意事项，阅读并同意所有注意事项后，触摸[是]。 4-4。如果您从 1.40 或更高版本更新固件，确认对话框建议备份设置和内存，触摸 [YES]。我们建议您在此步骤中对其进行备份，因为更新固件后可能会重置所有设置和记忆。 – 如果您从 1.30 或更早版本更新固件，请跳过此步骤，然后对讲机显示固件选择屏幕。 4-5。备份文件制作完成后，出现固件选择界面，点击固件更新数据（例如7300_141）。 4-6。请仔细阅读所有注意事项，当您要执行时，触摸[是] 1 秒钟开始固件更新。 4-7。更新完成后，“固件更新已完成”。显示，对讲机将自动重启。 5. 如果设置和记忆已被重置，请将已备份的设置和记忆加载到 SD 卡上。 5-1。在菜单中显示 SD CARD 屏幕。 5-2。轻触 SD CARD 屏幕上的“Load Setting”以打开 LOAD SETTING 屏幕。 5-3。触摸已保存文件的文件名。 5-4。触摸“ALL”，然后会出现对话框“加载文件？新的“REF Adjust”设置将被保存。” 显示，触摸[是]。 5-5。加载结束后，“完成！重新启动 IC-7300。” 显示，重启对讲机。更新固件后，OTHERS Set 中的版本信息如下。主 CPU：1.41 DSP程序：1.07 DSP 数据：1.00 FPGA：1.13

树莓派4B设置USB启动

我们先要了解一下4B之前的版本的启动流程，主要分为四个阶段：

GPU读取芯片上一个ROM的内容并执行
ROM中的程序挂载SD卡并加载第一个FAT分区上的bootcode.bin
bootcode.bin从FAT分区加载start.elf
start.elf从FAT分区加载kernel.img，然后唤醒CPU,CPU开始执行kernel.img
从这个流程中可以看到，第一阶段的BootLoader是从芯片上的ROM中读取的，ROM里的代码是出厂定制好的后期不能再改变。然而随着4B的硬件升级，USB被移到了PCIe总线，网卡也用了新的型号，再加上4B启动过程和SDRAM的设置远比之前的型号要复杂的多，继续使用集成在SoC ROM中的代码是有很大风险的，所以4B增加了一块EEPROM来解决这个问题，启动程序写入到EEPROM中来取代bootcode.bin的工作，启动程序的bug修复和新功能添加都方便了很多。

VMware vCenter Server Workaround Instructions for CVE-2021-21972 and CVE-2021-21973 (82374)

发表于2021年2月24日由Bi4Qzw

Purpose

The vCenter team has investigated CVE-2021-21972 and CVE-2021-21973 and have determined that the possibility of exploitation can be removed by performing the steps detailed in the ‘workaround’ section of this article. This workaround is meant to be a temporary solution until updates documented in VMSA-2021-0002 can be deployed.

Impacted product versions:

7.0 prior to 7.0 U1c
6.7 prior to 6.7 U3l
6.5 prior to 6.5 U3n

Functionality Impacts:
Functionality impacts are limited to environments that use vRealize Operations. It should be noted that the vulnerable endpoint exists in vCenter Server whether or not vRealize Operations has ever been introduced to the environment.

New vRealize Operations customers will not have the provision/option to auto install & configure the vRealize Operations Appliance through the plugin.
Customers who have already configured a vCenter Adapter in vRealize Operations with vCenter will not be able to display the metric & alert details (both VC & vSAN overview widgets) in the vCenter H5 client.

Resolution

Resolution for CVE-2021-21972 and CVE-2021-21973 is documented in VMSA-2021-0002.

Workaround

To implement the workaround for CVE-2021-21972 and CVE-2021-21973 on Linux-based virtual appliances (vCSA) perform the following steps:

SSH to vCSA.
Take a backup of the file:

/etc/vmware/vsphere-ui/compatibility-matrix.xml

Content of this file looks like below :

Using a file Editor, Insert the below line in the file.

. . . .

</pluginsCompatibility>

</Matrix>

The file should look like below

Restart the vsphere-ui service. Using command: service-control –restart vsphere-ui
Navigate to the https://<VC-IP-or-FQDN>/ui/vropspluginui/rest/services/checkmobregister. This page displays 404/Not Found error (as shown below).

From the h5-client, the VMWare vROPS Client plugin can be seen as “incompatible” under Administration Solutions  client-plugins as shown below

This confirms that the endpoint /ui/vropspluginui is disabled.

To implement the workaround for CVE-2021-21972 and CVE-2021-21973 on Windows-based vCenter Server deployments perform the following steps:

1. RDP to the windows based vCenter Server.
2. Take a backup of the file –

C:\ProgramData\VMware\vCenterServer\cfg\vsphere-ui\compatibility-matrix.xml

3. Content of this file looks like below :

4. Using a file Editor, Insert the below line in the file.

    <Matrix>
<pluginsCompatibility>
  . . . . 
  . . . . 
<PluginPackage id="com.vmware.vrops.install" status="incompatible"/>
            
          </pluginsCompatibility>
    </Matrix>

5. The file should look like below:

6. Restart the vsphere-ui service. Using command – C:\Program Files\VMware\vCenter Server\bin> service-control –restart vsphere-ui
7. Navigate to
https://<VC-IP-or-FQDN>/ui/vropspluginui/rest/services/checkmobregister.
This page displays 404/Not Found error (as shown below):

8. From the h5-client, the VMWare vROPS Client plugin can be seen as “incompatible” under Administration Solutions  client-plugins as shown below:

This confirms that the endpoint /ui/vropspluginui is disabled.

To revert the workaround for CVE-2021-21972 and CVE-2021-21973 on Linux-based virtual appliances (vCSA) perform the following steps:

1. SSH to vCSA.
2. Using a text editor edit the file –

/etc/vmware/vsphere-ui/compatibility-matrix.xml

3. Remove the below line in the file.

   <Matrix>
<pluginsCompatibility>
  . . . . 
  . . . . 
<PluginPackage id="com.vmware.vrops.install" status="incompatible"/>
            
          </pluginsCompatibility>
    </Matrix>

4. Restart the vsphere-ui service. Using command – service-control –restart vsphere-ui
5. Validate that the vSphere-ui service is up. VMWare vROPS Client plugin status is deployed/enabled

To revert the workaround for CVE-2021-21972 and CVE-2021-21973 on Windows-based vCenter Server deployments perform the following steps:

1. RDP to the Windows vCenter Server.
2. Using a text editor edit the file –

C:\ProgramData\VMware\vCenterServer\cfg\vsphere-ui\compatibility-matrix.xml

3. Remove the below line in the file.

    <Matrix>
<pluginsCompatibility>
  . . . . 
  . . . . 
<PluginPackage id="com.vmware.vrops.install" status="incompatible"/>
            
          </pluginsCompatibility>
    </Matrix>

4. Restart the vsphere-ui service. Using command – C:\Program Files\VMware\vCenter Server\bin> service-control –restart vsphere-ui
5. Validate that the vSphere-ui service is up. VMWare vROPS Client plugin status is deployed/enabled
