EFUSE read/write VDD_SDIO from user application

Thanks WiFive - that worked. I was at 80MHz DIO, which apparently worked at 3.3V and apparently passed the data hash checks (??) but at 40MHz it flashes and runs just fine:

My next question - is it possible to check if the efuses are burned at runtime and burn them through my software? (for devices already in the field) Thanks.

Thanks. When I set the voltage to 1.8V, everything runs just fine with 40MHz flash speed, but when I try to use my OTA WiFi-based reflash mechanism, there are a lot of write errors:

Flashing error: 0010621F

Flash error and closing socket


In this case, it got 0x621F bytes in, and then was unable to write offsets 352-384 in the incoming packet, even after 10 attempts. Note that this code works perfectly at 3.3V. I'm wondering if I need to do something to change the speed at which the esp_ota_write function is writing?? Thanks for any insights.

[WiFive]

You mean if you then reflash it at 1.8v over uart it works fine or is there a chance the flash is damaged?

[iosixllc]

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.

If I skip the write verify and let it complete, I get this:

I'm also confused why the checksums don't match between the two esp_image lines.

My theory is the read speed at 80MHz is being set inside the ESP32, but when I write at the same speed, I have a problem...

[WiFive]

What sdk version are you using?

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 bytes of the content, total 682291 bytes
Received 1436 bytes (2404/682291)

E (50527) upgrade: Failed to write flash at address 0x00100DFE, error 0 [1160] 02401700 = 2240DFFA [1436]

etc... aborts.

On the right side is what came out of the read from flash, the left side is what was supposed to be written. Thanks.

You have this enabled in your sdkconfig?
https://github.com/espressif/esp-idf/bl ... config#L16

Have you tried both DIO and QIO @40mhz?

Have you tried if an updated bootloader makes any difference?

Can you reproduce with ota example?

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.
