our new board uses “a10soc” , we need bring soc up firstly when the board comes back. The first target is uboot (preloader) I guess ~
Can anyone tell how to generate u-boot image which matches to our current quartus pro 19.2 too chain ? where can I find the appropriate u-boot source code to fit our customer board ? Thanks
thanks @EBERLAZARE_I_Intel ,
I had followed this link you shared to compile the uboot.bin in SD-Card,
Another “stupid” question : Whether a special FPGA GRSD Image is needed to be run firstly, before u-boot runs on ARM SOC ? because I guess FPGA image should firstly initialize hardware fabric for SOC interconnection, then ARM can run up successfully. Is this correct ?
If it's the case, where I can put FPGA image for power up to run. Thanks in advance
The design would depend, you may load it first or later. In Arria 10 there is a special feature which uses Early IO release feature, which calibrate the DDR, IO, peripheral at early stages in order to boot-up faster than normal booting sequence:
But for starters, you may want to refer here for full grasp understanding:
