We found a symptom that iteflash always programming EC failed on a specific host machine. For this failed case, it is caused by the incomplete read from ftdi_read_data(). For example, we want to read 32 bytes by just call ftdi_read_data() one time, but ftdi_read_data() may return (number of bytes read) 10 or 20 but just not 32. This change will call ftdi_read_data() again and again until all data is read. Change draw_spinner() function to use fprintf(). We will show percentage increase from 0 percent to 100 percen during verifying. Change of flash_ec script: Move operations of reinitialize ftdi_i2c interface to cleanup() and we won't miss them if programming is failed. BUG=none BRANCH=none TEST=To run iteflash on that host machine and flashing is done.
