Subject: Why is USB_BOOT_IO_BLOCKS set to 128?
Date: Wed, 19 Oct 2016 09:57:05 +0800	[thread overview]
Message-ID: <47a8c44f-e72f-a993-a0a0-0ee38d2735d3@linaro.org> (raw)

Dear experts,

Could anyone help to explain why USB_BOOT_IO_BLOCKS in 
MdeModulePkg/Bus/Usb/UsbMassStorageDxe/UsbMassBoot.h is set to 128?

We found on some platforms this value may cause USB boot failure and 
*64* blocks will make them work. Though we have not got the final root 
cause, it will be really helpful if you can tell the reason of setting 
it to 128 and possible root cause for such issue.

Thanks and regards,

Heyi
