Re: BT_HCI: host_recv_pkt_cb couldn't aquire memory for inbound data buffer.

I am also having a similar problem. Is there any way we could actually release/clear the memeory. BLE Stack is completely getting stuck and no memory left after burning out all the memory with incoming and outgoing data. Is there any mechanism that we could do in order to avoid such situations

But when trying with JTAG alone , facing same issue. Don't know what is the problem.

Re: esp32 -Jtag Programming

Solved. You should include reset command while flashing the board.
openocd -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp32-wrover.cfg -c "program_esp32 firmware.bin 0x10000 verify reset exit"

Re: esp32 Update from spiffs

I see at least two issues casually browsing through your code. There may be more, but these I noticed: Minor but potentially killing: You use fread in such a way that it fails to read the last bytes of data if the size of the update file is not a multiple of 1024. (nmemb vs size arguments) Major an...

Re: esp32 Update from spiffs

FYI, the partition table would be *a* reason why this could not work, but given that you now corrected it and you still have the error, it's not that. Perhaps you can show the code you're using? Maybe that helps us. Please find the attached snippet void ota_task(void *pvParameter) { esp_err_t err; ...
