On v3.2.2, testing with an Infineon SLB9673 resulted in the following error when attempting to read from a previously written NV index. Upgrading to the latest release, v4.1.3, resolves the issue: ```shell ~# tpm2_nvread 0x1900001 WARN: Reading full size of the NV index ERROR:esys:../tpm2-tss-3.2.2/src/tss2-esys/esys_iutil.c:1096:esys_GetResourceObject() Error: Esys handle does not exist (70018). ERROR: Esys_SequenceComplete(0x70018) - esapi:The ESYS_TR resource object is bad ERROR: Failed to get shandle ERROR: Failed to read NVRAM area at index 0x1900001 ERROR: Unable to run tpm2_nvread ``` Between v3.2.2 and v4.1.3, the most notable update is v4.1.0 [1], which includes a fix for CVE-2024-29040, along with 40+ bug fixes and 10+ new features. Bumping to v4.1.3 adds access to these improvements and addresses the NV index read issue.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
