Re: ESP32 as ISP

I finally managed to program the external flash using the ESP32 core for Arduino IDE and two more components: 1. SPIFFS: https://github.com/espressif/arduino-esp32/tree/master/libraries/SPIFFS 2. A cool library developed by Marzogh: https://github.com/Marzogh/SPIMemory For uploading the 3 binaries (...

Re: EFUSE read/write BLOCK 1/2/3 from esp-idf

@WiFive Thank you sir! :ugeek: That was exactly what I was looking for. What's the main difference between calling: REG_SET_FIELD(RTC_CNTL_SDIO_CONF_REG, RTC_CNTL_XPD_SDIO_REG, 1); and REG_WRITE(EFUSE_BLK0_WDATA4_REG, EFUSE_RD_XPD_SDIO_REG); They both seem to do the same thing. In case anyone is loo...

EFUSE read/write BLOCK 1/2/3 from esp-idf

How would one do the writing of EFUSE BLOCK 1/2/3 and then the reading of EFUSE BLOCK 1/2/3 (to check that the write was successful) in esp-idf? I'm well aware of: 1. https://github.com/espressif/esp-idf/blob/master/components/bootloader_support/include/esp_efuse.h 2. https://github.com/espressif/es...

@Veder_Mester
Did your experiments show better results?

Re: External flash component

Sorry for the late response; I was out of country for the last week and didn't have the ESP32 with me. I don't see how that bug got past me; I was very well aware of GPIO MUX frequency limitations... :oops: I will check it right away and post an update. Update 1: I'm getting some strange results; On...

Re: External flash component

I guess we've posted the reply at the same time :lol:
From what I see using native VSPI pins seem to get the write methods to work, but changing the SPI via GPIO MUX yields the same results that I was posting. Hmm...m

Re: External flash component

Routing the SPI interface trough GPIO MUX might be the culprit.
So I guess it works for you, lllucius. Does it?

Re: External flash component

Grasping at straws here, but when was the last time you updated your esp-idf SDK? There was a bug I'd reported that "may" be relevant here and it was fixed on December 12th: https://github.com/espressif/esp-idf/issues/1549 So i was on: ESP-IDF v3.1-dev-380-gca3faa61 2nd stage bootloader N...

Re: External flash component

Thanks for the tip! I think that I might have found out what's the problem: register 1 and 2 seem to not be set up properly. But why? I will take a closer look into this and come up with an update when I figure it out. ERASE/WRITE/VERIFY Test... Bus dual 1-1-2 Flash size 8388608 Sector size 4096 Reg...
