Hi,

I have an eclipse project which I'm building  for x86 and for i.mx53 .

The code is loading firmware through the UART2 or UART3 at 115200 bps to a modem chip and and  making alive checks (custom board) .

 

The  code works for x86 and fails  for mx53 .

I observed  the uart Tx pins with a port monitor SW  and realised that some piece of the sent packet is missing  or repeated .

 

I thought its an alignment problem but the sendbuffer is aligned to four bytes :

} __attribute__((aligned(4),packed)) str_fwbuf;

 

 

Any comment?
