Hi all,
just to inform, seems xyzModem is not following the protocol spec of YModem:
YMODEM Batch Transmission Session (1 file)
SENDER RECEIVER
<-- C (command:rb)
SOH 00 FF foo.c NUL[123] CRC CRC -->
<-- ACK
<-- C
SOH 01 FE Data[128] CRC CRC -->
<-- ACK
SOH 02 FC Data[128] CRC CRC -->
<-- ACK
SOH 03 FB Data[100] CPMEOF[28] CRC CRC -->
<-- ACK
EOT -->
<-- NAK
EOT -->
<-- ACK
<-- C
SOH 00 FF NUL[128] CRC CRC -->
<-- ACK
After first EOT u-boot send an ACK, not correct.
Same behavior using SOH or STX.
Regards
angelo
