Flash erase/write/read test failing
I am running the following code, to perform a regression test on the flash memory, and am getting a lot of errors. Note that before, when we were running VSDIO @ 3.3V (D2WD), the flash was working perfectly. Once we set the fuse for 1.8V, these errors started, and I'm sorry to say we are still seein...

Issues flashing D2WD/flash status meaning?
Hi - am getting this issue on some D2WD devices - sometimes they will flash a few times and then start doing this: $ make -j 32 flash project.mk:53: esp-idf build system only supports MSYS2 in "MINGW32" mode. Consult the ESP-IDF documentation for details. project.mk:53: esp-idf build system only sup...

Re: EFUSE read/write VDD_SDIO from user application
Thanks Angus, Yes, you understand the problem correctly. We are seeing the behavior on ~30 chips, many of which were not ever run at 3.3V. 20MHz seems to have no effect. We have the standard 0.1uFs all around plus 1uF and 10uF near the antenna pad power inputs. Also, bulk 47uF capacitance maybe 10-2...

Re: EFUSE read/write VDD_SDIO from user application
Ok then I do have the latest bootloader. It seems if I could slow the write speed that would be ideal. I’m at 3.3V with VSDIO at 1.8V.

Re: EFUSE read/write VDD_SDIO from user application
I do have that enabled in sdkconfig. I have only tried DIO. I was not aware there is an updated boot loader - would that have come with the new esp-idf? I haven’t tried the OTA example, but I will say this code works 100% at 3.3V.

Re: EFUSE read/write VDD_SDIO from user application
I was using 2.1 beta, I just updated to HEAD along with the latest compiler update, and am getting the same result: I (47010) upgrade: OTA Partition: 3FFD8E30 I (47010) upgrade: Set start address for flash writes to 0x00100000 I (50380) upgrade: Result from esp_ota_begin: 0 1 So far we have 968 byte...

Re: make flash errors
I just downloaded the new SDK - esp32_win32_msys2_environment_and_toolchain-20170918.zip
This doesn't seem to include python, so I downloaded 2.7, but it doesn't recognize windows COM ports. Is there a special python release I need? Thanks!

Re: EFUSE read/write VDD_SDIO from user application
If I skip the write verify and let it complete, I get this: I (150478) upgrade: OTA Partition: 3FFB71BC I (150480) upgrade: Set start address for flash writes to 0x00100000 I (153751) upgrade: Result from esp_ota_begin: 0 1 I (165284) esp_image: segment 0: paddr=0x00100020 vaddr=0x3f400020 size=0x13...

Re: EFUSE read/write VDD_SDIO from user application
Correct, UART flash works just fine at 1.8V and 40MHz. OTA flash at 1.8V is erroring out consistently. I'm using fresh devices just in case there is an issue with the old ones. Fresh devices without 1.8V set (@3.3V) work fine via OTA.
