From 11758a56ab96c216512606ca470a72026e8d45ce Mon Sep 17 00:00:00 2001 From: Alberto Panizzo Date: Thu, 12 Jul 2018 13:05:46 +0200 Subject: usb: rockchip: be quiet on serial port while transferring data While downloading or uploading megabytes of data we had thousands of printf in console like: transfer 0x10000 bytes done OR Uploading 0x1000 bytes This because transfers are chunked and there is no way on target side to know the overall transfer size (to print one string per overall transfer). All these prints on serial console do slow down significantly the transfer and does not offer a significant information to the developer: rkdeveloptool and Rockchip original tool do use small chunks read/writes on big transfers. This allows on workstation to print percentage of transfer complete and as well offers to developer the information about: transfer is running OK. On error, either the percentage will stop or an error will be shown on workstation console.
