Re: NVS分区生成器用于量产UID应该怎么使用好

Perhaps you can generate multiple NVS binaries using the mass manufacturing utility? https://docs.espressif.com/projects/esp ... s_mfg.html

Re: can't OTA .bin file from SD card

zoro99: if by "same thing" you mean reading an OTA binary image, then consider using fread function instead of fgets. The latter is meant to be used for text files, while the former will also handle 0x00 bytes which can be found in a binary file.

Re: ULP RTC Slow memory

Code: Select all

range 32 8192 if ULP_COPROC_ENABLED
This is a bug in Kconfig, thanks. The range should be 16 ... 4096.

Re: ROM Serial Bootlader

No, this is not possible. ROM download mode can only be triggered by strapping pins configuration. It can also not be entered from IDF using a function call, as the ROM bootloader uses static memory range which is used in IDF for the heap. You can however use the esp_ota_* APIs to perform an update....

Re: Core dump providing no info at all

This output means that GDB has failed to recover anything useful about the main task.

However you can try using 'dbg_corefile' command instead of 'info_corefile', which will start an interactive GDB session. Then switch to another task and do 'backtrace'.

Re: SD card and file seek problem

Could the file mode be an issue?

SD.open(Files[0]->name, FILE_WRITE);

To read and write a file, r+ or w+ modes should be used.

Re: ULP with JTAG?

Hello Pascal, it is not possible to debug ULP code using JTAG. The ULP doesn't have a debug interface.

Re: JTAG Debugger

For the one you have linked, that would be jlink.cfg (not in ftdi directory).
