Hello JP. Have a nice day! I already several times face the following problem. At the first start, I get an error of the RDA module.

E (6729) i2c: Z:/esp/esp-idf/components/driver/i2c.c:1008 (i2c_master_read):i2c data read length error ESP_ERROR_CHECK failed: esp_err_t 0x102 at 0x401360ff file: "Z:/msys32/home/Alex/Karadio_orig_096/components/RDA5807/common.c" line 67 func: i2c_slave_read_only expression: i2c_master_read(cmd, buf,len-1, ACK_VAL)

Entering gdb stub now. $T0b#e6

The firmware is standard, taken from here. The electrical circuit is also taken here. It seems to me that this is due to the choice of display. I chose type 0 (do not use). This causes a device conflict on the I2C bus when testing a non-existent RDA module Tnx. Alex.

Yes, i must see this point. I am integrating the rda module, but not finished.

I removed the RDA dependency.
