Re: Unstable partition API flashing functions

Thanks Imtiaz. Regarding the Illegal Instruction exception crash, thanks for the crash dump it's extremely helpful. We're looking into that now. The bugfix/spiflash_lock_period branch is in the process of being merged and should appear in Github master branch very soon. Regarding the AP disappearing...

Re: 使用esp32芯片时,有芯片id或者其他不可修改的唯一号码吗?

I was also trying to determine how to use our IEEE allocated MAC block for the devices. You can't arbitrarily set the efuse assigned MAC addresses (apart from burning 0s to 1s), but you can set your own MAC address in software. EDIT: For Wifi you can use esp_wifi_set_mac(), other interfaces involve...

Re: Porting Code and File Organization

I added the component.mk file which contains: COMPONENT_ADD_INCLUDEDIRS=. When I #include <"libssh/libssh.h> it says "fatal error: libssh/libssh.h: No such file or directory" The libssh directory contains a directory called "include" which contains "libssh" which ...

Re: I2C SCL frequency 10% less than it should be at 400kHz

why expressif didn't just switch everything over to the working ones... Yes I wonder about that too. Is there any penalty to use the alt address? There is a performance penalty. The peripheral address registers from 0x3FF40000 are mirrored at the 0x600000 address, but this second address is via a s...

Re: wrover kit shematic V2 "SD Card"

Hi Rudi, IO12 is not pulled up on the board because it needs to be low on reset to enable 3.3V flash voltage. Refer to this note in the sd_card example README: https://github.com/espressif/esp-idf/blob/master/examples/storage/sd_card/README.md#note-about-gpio12 I found that on my ESP-WROVER-KIT boar...

Re: WROOM-32 (DevKitC) QIO/40MHz operation keeps resetting

Yes, it is a known issue. The boot code in the ROM of the ESP32 isn't directly compatible with the specific instructions the flash chip needs to use QIO mode. We are working on a workaround, expected to get into esp-idf in the coming weeks, but for now, QIO mode does not work here. Is there any upd...

Re: make menuconfig fails

Hi John, The build system tries to create mconf.o in the esp-idf/tools/kconfig directory. Permission Denied implies that the user running "make" doesn't have permission to write this file in this directory. Is it possible that you ran the "git clone" for IDF as root (ie with sudo...

Re: Discussion of QIO DIO QOUT DOUT flash modes?

This forum is for ESP32. For ESP8266 support, try bbs.espressif.com or other sites. After changing the mode to DOUT, it worked for this 'faulty' chip. Any idea how can i see which modes the chip support? There are two factors for which SPI flash modes work, but they don't depend on the ESP8266/ESP32...

Re: Unstable partition API flashing functions

I had a function that verifies the downloaded file from the spi flash using MD5 which has always worked - and it just stopped working with the update - it just freezes now when you call it and after a while I get a WDT reset - do you guys have any idea what could be happening. Can you please post t...
