Linux LVM Snapshots LVM snapshots. Investigating some backup issues I decided to give them a try to see if they can help. This was done on CentOS 7. First, the important detail: the LVM snapshot lives in the same volume group as the logical volume one is making snapshot of. So, if...
This solution is mostly for Raspberry Pi 4 and 5 owners, as these models use an EEPROM chip to store their boot code instead of keeping it on the SD card like previous models did. Start by downloading the latest version of the Raspberry Pi Imager from the official Raspberry Pi website. ...
In a call to onie_efi_boot_clean.sh without parameters, all NOS EFI boot entries will be cleared, leaving only ONIE enabled. onie_efi_boot_clean.sh Help can be accessed by executing the following command: onie_efi_boot_clean.sh-h ...
The problem is when the average consumer goes out shopping for memory or a storage device, s/he primarily looks at the capacity or size without considering the speed (read/write). Having a bunch of space is great but waiting around for hours for something to load or write to your hard d...
Please refer to the Workflow 3: How to flash to an external storage in Linux_for_Tegra/tools/kernel_flash/README_initrd_flash.txt For your case, you could use the following command to flash into an external NVMe SSD: $ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device ...
error code is at the end of the log in my original post:[00:001:00:01]: Intel(R) Ethernet Converged Network Adapter X710adapters/nul_gen_device.c:_NulGenReadMacAddress:121: NalReadMacAddressFromEeprom not supported MAC address type [0x6]nul_device.c:NulGetF...
Battery Holder:It allows the module to keep running when the external power is absent. RTC Chip:This chip maintains the time and date. AT24C32 EEPROM:It provides non-volatile storage for data logging and other purposes with 1,000,000 write cycles. ...
1) What is the commands in uboot and Linux to check availability of NOR flash 2) Is there any way to update NOR with new uboot and kernel from kernel. 3) When we call saveenv in uboot prompt, Where will the environment variable get saved. Is it in NOR or EEPROM?
read/write Flash/EEPROM memory on NIC When a driver wants to configure packet reception, it accesses the following set of configuration registers: Receive Control Register - enables/disables packet reception, configures RX filters, sets the RX buffer size; ...
These steps work for all current releases of the Raspberry Pi. Even though versions since the Pi 4 also have what is called an EEPROM, the firmware is still handled the same way. Please feel free to leave a comment below if you have any questions about updating firmware on your device. ...
