keil developpement board (MCBSTM32F400, STM32F407)
CPU Clock : 168Mhz from HSE.
USB Speed : High speed
USB Class : MSC - mass storage device
ULPI : STULPI01B
I use STM32F105/7, STM32F2 and STM32F4 USB on-the-go Host and device library.
I am trying to read a USB memory.
If it only reads once, it succeeds.
But if it reads repeatedly, an error interrupt will occur.
error interrupt :
OTG_HS host channel-x interrupt register
Address offset: 0x508 + (Channel_number × 0x20)
Bit7 : TXERR
(RM0090 Reference manual, page 1124)
Is the solution of this error known?
