Re: Destroy key stored in eFuse block

Hi @eitell! There might be some solutions: - an efuse block is already read-protected - Software can not read it anyway, so it is safe to keep it. If you still want to destroy data see below. - an efuse block is write-protected - The data in this block can not be changed. - an efuse block is not wri...

Re: Where is EFUSE_DIS_PAD_JTAG ?

Hi!
Sorry for the inconvenience. The name in the doc is DIS_PAD_JTAG, but in the IDF and espefuse.py it is HARD_DIS_JTAG (they point to the same efuse bit). Please use HARD_DIS_JTAG for now. We will fix it soon, so after that, both names will be available.

Re: esp-idf sample code for efuse fails for esp32-s3

Hi!
Please take a look the github thread - https://github.com/espressif/esp-idf/issues/8810
You need to change the names in your custom_efuse_table.csv

USER_DATA.MODULE_VERSION, EFUSE_BLK3, 56, 8

Final efuse name - USER_DATA_MODULE_VERSION

Re: Issue with Secure Boot V2 : Sig block 0 invalid

Hi regiskiwi! I have checked the branch that you used ESP-IDF v4.3-274-g75940e9364 in the first msg and I successfully run the Secure Boot V2 on esp32 eco3 (the first and the next boots are ok). As I understand last your msg with the ESP-IDF v4.2 (you did not provide what exact version). I think tha...

Re: Issue with Secure Boot V2 : Sig block 0 invalid

Hi regiskiwi! It is hard to say what it is. I think.. it looks like the bootloader was corrupted. Th size of bootloader = 13124+20616+4104 = 0x93D4 + 0x1000 (offset) = 0xA93D4 => round up 0xB000 => + signature block => 0xC000. Your partition offet is 0xE000 (looks good). verifying bootloader: D (617...

Re: OTA update with secure boot enabled fails with error "image has invalid signature version field 0xffffffff" [IDFGH-4

Hi sripad! I am able to see the same log as here ` secure_boot_v1: image has invalid signature version field 0xffffffff`. This happens when you try to provide not a signed app to OTA server. - disable "Sign binaries during build" - provide `Secure boot public signature verification key` - signature_...

Re: ESP32 OTA Anti-Rollback with Factory Partition.

Hi NotMyRealName! NOTE: I have it configured to launch the test app from a GPIO pin boot, but as the default behavior is to run the test app if no other partitions are found this is a bit of a security hole. You could very easily force running insecure code by corrupting or loading invalid code onto...

Re: gettimeofday not working with timeval [IDFGH-3263]

Hi @halilarkl07! I tried your code and can not get the same result as you reported (it works as expected). I used the hello_world example as a base and put your code. I suggest you try my way, apply the hello_world_patch.txt patch for hello_world. The log like this: tv_now.tv_sec 0 PRId64 tv_now.tv_...

Re: DPORT access workaround and high interrupts.

Hi Malishev.

Thank you for your report about it. We have fixed this recently - https://github.com/espressif/esp-idf/co ... 3dbc2d066b.
This fix disables interrupts up to 5 levels for two DPORT workarounds. (will merge it as well to 3.3, 3.2 and 3.1).
