burn files to external flash

Hello All,

I need to burn a bunch of files to the external flash, which I am going to access with VSPI interface. Are there any flasher/burner programs that go with openocd to get this thing done? or is there any tool/driver to do it? any pointers to this will be helpful.

Thanks,
SD

unable to install packages on msys

Hello all, I downloaded the readily available msys2 & toolchain packages from https://docs.espressif.com/projects/esp-idf/en/latest/get-started/windows-setup.html#toolchain-setup. I see that I will also need cmake to be installed as I am using a third party component which uses cmake. When I do "pac...

Re: New Wroom-32 modules JTAG Problem

It seems like even I am facing the same issue. I got few new ESP-WROOM-32d modules which don't respond to any JTAG requests. I am able to program/debug the WROOM module in ESP-EVB launchpad with help of JTAG but I am not sure why same thing doesn't work on new modules. Even I have a feeling that mod...

Re: Read/Write to NVS with DIRECT ADDRESSING

On power up Master writes all the available data to EEPROM. I would say this is a discrete data that comes through CAN interface. Thereafter, when some configuration in the Master changes, the exact byte with its exact address location will be sent to update in the EEPROM. In worst case scenario we ...

Re: Read/Write to NVS with DIRECT ADDRESSING

Hi ESP_Sprite, Well, the Master that will be sending around 4KB of data to ESP32 has historically maintained a format. The Master will have the same 4KB data stored in an EEPROM. The Read/Write instructions from Master to EEPROM are all address based and these are communicated through CAN interface....

Read/Write to NVS with DIRECT ADDRESSING

Hi All, I have had enough information about writing to NVS using key/value pair and by using File Systems. These seem to make things much easier for some cases but for my application I would be better off writing to NVS with direct addressing with help of spi_flash_{read|write|erase} API's. Is it po...
