Micro USB problem (STM32F429)

[FSant.1]

Hi, 

I'm using an STM32F429 zi board. I'm saving data in the SDRAM and then I'm reading it and sending it to TeraTerm with the micro USB connection.

But there is some problem with the micro USB connection because TeraTerm detect the board but it doesn't receive information, I supose that can be a driver problem.

Just in case, I put the reading and sending code here:

for (i = 0; i < 10; i++) {

Read = TM_SDRAM_ReadFloat(aux);

Read2 = TM_SDRAM_ReadFloat(aux+8);

Read3 = TM_SDRAM_ReadFloat(aux+16);

Read4 = TM_SDRAM_ReadFloat(aux+24);

Read5 = TM_SDRAM_ReadFloat(aux+32);

//Read6 = TM_SDRAM_ReadFloat(aux+40);

aux += 40;

sprintf(&chain,"%f %f %f %f %f  \r\n", Read , Read2, Read3, Read4, Read5);

Read5, Read6); 

TM_USB_VCP_Puts(&chain);

Delayms(5);

}

TM_USB_VCP_Puts("];");
