[U-Boot] Hi All, is anybody involved into Renesas SH development?
Good morning, if any of you is involved in such a develop, I'd like to have discussion if possible about u-boot onto sh architecture
Thanks in advance
Best regards

You're probably aware, that U-Boot is already running on SH. So, just post your specific questions, you might want to CC U-Boot SH maintainer, if you like.

Hi Guennadi. I saw your work about sh mobile. I have these problem: 1) I have my own board a little bit different than rsk7203; much NOR flash; much SDRAM; 2) To know better the structure I'd like to run from NOR flash without reloc. How can I change noot.lds?
I'd not have the email of Nobuhiro Iwamatsu. Do you have?

Sorry, I'm not involved in U-Boot development on SH, I just pointed out, that it exists and is maintained.
I'd not have the email of Nobuhiro Iwamatsu. Do you have?
Why don't you just look in the MAINTAINERS file in U-Boot sources?

Thanks Guennadi. I hope Nobuhiro san would answer to me.
This is my condition. I have derived a board based on rsk7203 keeping in mind the hw of rks7203. But I used 8 MBytes of Nor FLASH and 64 MBytes of SDRAM. I have potred the linux-2.6.17 given with rsk7203 and I developed the kernel driver for my specific application and I have developed the custom application need. The linux kernel give with rsk7203 is done by MCP data, and the solved the problem of boot the board having a minimal boot loader written by them that: 1) initialize the hw SDRAM, LCD Controller; 2) jump to the 0x40000 address where is linked the kernel zImage that by itself uncopress and run. Everything works, but: 1) I cannot upgrade the kernel using ethernet; 2) I cannot boot using bootp or tftp; 3) the eth has strange behaviour but I'm not able to understand if it is a kernel driver problem or hw problem
So I decided to migrate to latest linux kernel and toolchain, and to use u- boot as boot loader.
As in tennis sport I tried the first service; I compiled u-boot for rsk7203 and downloaded it at 00000000 address with E10B emulator. But it doesn't work.
SO I ask. 1) which config params I need to change to keep in mind different size of flash and different size of ram and the fact that my ram is 32 bit wide? 2) Is it possible to build u-boot in a very minimal way to running it directly from flash using the on chip ram?
Thanks in advance.
