Re: Keep JTAG enabled alongside flash encryption

Thank you for your answer. You said flash encryption would be useless as the attacker could read the flash through JTAG, but if flash encryption is enabled, he would not be able to decrypt it, right?

Keep JTAG enabled alongside flash encryption

Hi,

I am currently looking for a way to keep JTAG enabled when flash encryption is also enabled in release mode. Basically, I would like to be able to erase the flash completely, and then reprogram it even if the flash encryption is used. Is there any way to do that?

Re: xTaskNotifyWait ulBitsToClearOnEntry and ulBitsToClearOnExit example

Alright so ulBitsToClearOnEntry and ulBitsToClearOnExit only has an effect on the notification state, but the value (in my example 1 << 0) remains unchanged. I am not sure why we should clear wether on entry or on exit. What is the difference in my case ? (even though I only set to 1, but let's say ...

Re: xTaskNotifyWait ulBitsToClearOnEntry and ulBitsToClearOnExit example

Correct. If you still needed to clear the value, you'd use ulTaskNotifyValueClear(...), but that wouldn't be atomic w.r.t. the receiving of the notification which, depending on the algorithm/use case, may or may not be a problem. If I understand correctly, the bits I set in the Task1 would not be c...

Re: xTaskNotifyWait ulBitsToClearOnEntry and ulBitsToClearOnExit example

Thank you for your answer,

So, what happens if I set both ulBitsToClearOnEntry and ulBitsToClearOnExit to 0? The value is not cleared at all?

xTaskNotifyWait ulBitsToClearOnEntry and ulBitsToClearOnExit example

Hi, I have been trying to use FreeRTOS task notification on ESP32 for a few days, and I am not sure I really understand the effect of the ulBitsToClearOnEntry and ulBitsToClearOnExit parameters of the xTaskNotifyWait() function. I am able to send notifications between 2 tasks with xTaskNotify() and ...

Re: Avoid certificate substitution during OTA

Hi aeropagz, To avoid certificate substitution, you may need to create a file system partition in the ESP32 flash (like SPIFFS or FatFS). To do so, you need to use a custom partition table (see Partition Table menu in sdkconfig of your project) where you add a fiel system partition. Inside of it, yo...

JTAG programming ESP32-C3 devKit M

Hi, After successfully flashing my code using a JLINK and JTAG pins( TDO, TDI, TCK and TMS) of an ESP32-S2-SAOLA-1 board, I tried to do the same with an ESP32-C3-DevKitM-1, following the instruction given here : https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/api-guides/jtag-debugging/...
