Hello,
I encounter an issue with spi_flash_read function. I'd copy uboot from SPI Flash to DDRAM. If I use the function once. It works OK. If I use the function is more than 1 time, then it doesn't work properly. Here is the procedure of what I did:
uboot version: U-Boot 2019.07-00013-g6107815c9c uboot size: 244288 Bytes
case 1: - Copy uboot to 0x81000000 -> Jump to uboot at 0x81000000 OK
case 2: - Copy uboot to 0x81000000 - Copy uboot to 0x83000000 -> Jump to uboot at 0x83000000 NOK. Only able to load some parts of uboot and then hang.
I hexdump and do memory comparison between 0x81000000 and 0x83000000. The memory is different from i=78078.
Do I need to do something in between 2 copies to solve the issue? Has anyone experienced this issue?
Thanks for any help or suggestion. Dan
