Dhanuraj Pillai 0 Posted February 18 Share Posted February 18 (edited) Hello, Just a basic question about Pmod ESP32 has debugging and flashing support for Synopsys ARC EM4 and EM6 cores ? Is access of the cores via JTAG possible? Many thanks in advance! Regards Dhanuraj Pillai Edited February 18 by Dhanuraj Pillai Link to post Share on other sites
0 JColvin 439 Posted February 18 Share Posted February 18 Hi @Dhanuraj Pillai, Unfortunately, Digilent does not have any support regarding JTAG access for the Pmod ESP32. I did end up taking a look at the documentation I found from espressif's website here, and I am lead to believe that you would not be able to do any JTAG operations between the datasheet for the ESP-WROOM-32 datasheet, their JTAG configuration page, and the Pmod ESP32 schematic. Thanks, JColvin Link to post Share on other sites

Sorry for the delayed response as I was out of office. I did not dive deep, but my first impression also is that JTAG operations are not possible. However it might be possible to do software update/ reprogramming of the target flash (DUT) wireless using the communication channels UART/SPI. Is my understanding correct? The idea is to fulfil atleast reprogramming of a sealed sensor-> Wifi->ESP-WROOM-32->SPI/UART-> SYNOPSYS BASED MICROCONTROLLER. If this could be primarily achieved, I can start diving deep into interfacing. Thanks again in advance! Link to post Share on other sites
