ESP32 devkitc v4 with esp-prog
Hi. I'm trying to set up the ESP-Prog with my esp32, but it fails to even flash. It's configured to flash on COM21 using the FTDIBUS (v2.12.36.2) driver via UART. I'm using the vscode extension to configure it. I've connected ESP_EN to the EN pin, ESP_TXD to TX, ESP_RXD to RX, VDD to 3V3, GND to GND...

Re: How to increase .bss size for ULP?
CONFIG_ESP32_ULP_COPROC_RESERVE_MEM Should be the correct way of increasing it. Any chance CONFIG_ESP32S2_ULP_COPROC_RESERVE_MEM is defined in your sdkconfig as well? That could potentially overwrite the setting. Are you able to provide a simple example that reproduce this behaviour? If so I'd be h...

Re: How to increase .bss size for ULP?
Hello @jshnaidm when I change the RTC slow memory value via 'menuconfig' I see it in two places: sdkconfig:CONFIG_ESP32_ULP_COPROC_RESERVE_MEM=2048 sdkconfig:CONFIG_ULP_COPROC_RESERVE_MEM=2048 It looks like some options have been deprecated and replaced with others: https://docs.espressif.com/proje...

How to increase .bss size for ULP?
Hi. I'm using the vscode extension to program and build my project. I've used the SDK Configuration editor to increase the RTC slow memory reserved for the coprocessor, but regardless of how high I put it, it always tells me that the ram region overflows by 64 bytes: [3/83] Performing build step for...

Re: esp-32s1 reading RTC timer through ULP, getting garbage.
READ_RTC_REG(RTC_CNTL_TIME0_REG+2, 0, 16) This doesn't look right. Are you trying to read the upper 16 bits?: READ_RTC_REG(RTC_CNTL_TIME0_REG, 16, 16) Yeah! I got confused by the macro, I ended up just doing .set timer_top_16, (0x3FF48014 - DR_REG_RTCCNTL_BASE)/4 REG_RD timer_top_16, 0, 16 And I go...
