nothing wrong with the IC, removed it just for the price!! you can solder it just like updesh31 do, or ask for the seller
maybe we should add `assert(...)` to limit the buffer address, or change to copy with `uint8_t*` , but not so much efficient ``` for(i = 0; i < v_rx_len; i++)...
uart test code: ```c #include #include "fpioa.h" #include #include "uart.h" #include "gpiohs.h" #include "sysctl.h" #include "sleep.h" #define UART_NUM UART_DEVICE_1 uint8_t jpeg[] ={0xFF, 0xD8, 0xFF, 0xE0, 0x00, 0x10, 0x4A, 0x46, 0x49,...
Board: sipeed maix bit or dock, the open-ec firmware on the sipeed maix go board have bug when baud rate too high, so ignore it! when change the CPU clock...
for this test code, when change baudrate to 1.5M, it works correctly, but 921600 not, maybe change the CPU frequency can do.
I'll pack a new one later
