ADDING I2C U BOOT COMMANDS SOFTWARE
Some attention has been paid to make this software easily configurable and extendable. Biggest difference is that there is no command link and instead of queuing commands are sent directly to the I2C bus.
ADDING I2C U BOOT COMMANDS PATCH
Our 32 patches patch series adding TPM 2. The development of U-Boot is closely related to Linux: some parts of the source code originate in the Linux source tree, we have some header files in common, and special provision has been made to support booting of Linux images. So we implemented, contributed and upstreamed to U-Boot support for TPM 2.0. 4 kernel with the mainline U-Boot, add the following line to boot. Back when we worked on this topic in 2018, there was no support for TPM 2.0 in U-Boot, but one of customer needed this support. strip initial noise) and insert the setenv commands above manually.
Right click on the platform project -> build project. File -> New -> Platform project -> Create from hardware specification (XSA) -> Browse (Select zcu102.xsa) -> keep everything default (as attached screen shot below) -> Finish. ) our board is able to boot the Liunx kernel.Īs soon as, I try to enable and use the I2C interface in u-boot, the kernel isn't able to boot anymore. Bootlin’s contribution: U-Boot support for TPM 2.0. Launch the Vitis IDE by executing the vitis command. When configuring the basic Hardware (SD Card, UART, Ethernet. For instance, all monitor commands are implemented with the same call interface, so that its very easy to add new commands. Your board should then build, but will not work fully since there will be no I2C driver.
ADDING I2C U BOOT COMMANDS DRIVER
Now I have to switch to a the new u-boot build flow created on the sources: (2020.04) as described on: įor our custom board, I adapted the u-boot configuration and device tree blob of the Arria 10 SoC DevKit included in the sources. If the board does not already use driver model, you need CONFIGDM also.
ADDING I2C U BOOT COMMANDS MAC
With a small adaption, u-boot (2014.10) is able to read a MAC address from an external EEPROM connected through an I2C interface. Until now, I used an old u-boot build flow utilized Quartus and the bsp-editor. A list of U-Boot commands can be accessed while in the U-Boot prompt. The board boots from an SD Card, loading u-boot and than a Linux kernel. 2 I can read correctly the i2c eeprom from U-Boot via i2c-tools. How do you do it? By the way,I ported and used U-Boot 2011.09 for this purpose.I used i2c-tool over Linux but it says UU which means driver is used by Linux and it doesnt let me dump or anything else.I have an Arria 10 SoC device on our custom board. Firstly i read my eeprom, then i tried to write byte by btye.Then i read again but nth happened.Then i tried to fill with 0xAA again it didnt succeed. For example, the I2C driver is used to send and receive data from the following devices: PMIC (Power Module) Trusted Platform Module (TPM) Embedded Controller. I tried with U-Boot using I2C commands.You can see my logs below. The inter-integrated circuit communication (I2C) driver is the most-used driver in U-Boot for Chrome OS. but does this really is a show stopper for adding i2c eeproms to MTD layer You. We have custom Am335x board with eeprom.We want to shape our eeprom like BeagleBone (I mean name,version,serial etc…). okay, flash has blocked base access, while i2c eeprom can have byte accesses.
