Re: esp32s3 devkitc flash size detect error and not work

I'm having the same issue. Has anyone solved this? I (37) boot: ESP-IDF v4.4.5 2nd stage bootloader I (37) boot: compile time 10:43:45 I (37) boot: chip revision: v0.1 I (39) boot.esp32s3: Boot SPI Speed : 80MHz I (44) boot.esp32s3: SPI Mode : SLOW READ I (49) boot.esp32s3: SPI Flash Size : 32MB I (...

Re: Burning efuses in the factory / during manufacturing of a product

Yeah, I saw that, but we had problems getting esptool to install/work with Windows python. It would be great if it was a proper app and not a python script that you need to load all sorts of dependencies for (python, libraries, etc).

Burning efuses in the factory / during manufacturing of a product

Hi, We're in the process of setting up manufacturing for a product we're making that contains an ESP32 module. I found the awesome esp flash tool that lets us flash our factory image. However, there doesn't appear to be a similar tool to burn efuses. We need to burn the flash voltage efuse in order ...

Re: SDIO problems

Actually, I solved my problem. I had badly ported part of the esp slave code to the IMXRT. One of my low level functions was passing an invalid parameter. However, I did have to use SDIO_SLAVE_TIMING_NSEND_PSAMPLE on the esp32 slave side to get the IMXRT to be able to read data from it.

Re: SDIO problems

So, actually, for IMXRT to ESP32 the err = esp_slave_read_bytes(context, HOST_SLC0HOST_TOKEN_RDATA_REG, (uint8_t*)&len, 4); in esp_slave_get_tx_buffer_num was getting 0x00001000 in len but then doing some bit math and it ends up 0 at the end. Also, I tried all the permutations of SDIO_SLAVE_TIMING_ ...

SDIO problems

I've been trying to get the SDIO host/slave examples working on two ESP32 dev boards. I'm using the secondary SDIO pins (the ones that are also JTAG pins), not the pins that are used for the SPI flash. I went through all the rigamarole of adding pullups to the lines, dealing with GPIO12 and all that...
