sunxi_nand_spl reading zeros on NextThing C.H.I.P.
by Yevhenii Hrabliuk 02 May '21

02 May '21

Hello, I'm trying to get latest U-Boot to work on the NextThing C.H.I.P. After borrowing NFC config from the Chip Pro .dts, I can write the SPL to NAND after loading U-Boot via sunxi-fel and the bootrom will pick it up fine. So the "full" sunxi_nand.c works. SPL's sunxi_nand_spl.c appears to read all zeros however - I checked by adding prints in spl.c/jump_to_image_no_args(). Can someone please suggest possible things to try to make it work? I tried tinkering with the settings but I have no idea if that's even the issue. The NAND is a Toshiba "TC58TEG5DCLTA00"; NTC's settings for it are presumably [1] and sunxi_nand_spl.c autodetects the following settings: page_size:16384 ecc_strength:4 ecc_size:1024 addr_cycles:5 nseeds:8 randomize:0 Thanks.

[U-Boot] [PATCH] Adds basic support for ProxyDHCP
by lylejfranklin＠gmail.com 02 Dec '20

02 Dec '20

From: Lyle Franklin <lylejfranklin(a)gmail.com> - ProxyDHCP allows a second DHCP server to exist alongside your main DHCP server and supply additional BOOTP related options - When u-boot sends out a DHCP request, the real DHCP server will respond with a normal response containing the new client IP address while simultaneously the ProxyDHCP server will respond with a blank client IP address and a `bootfile` option - This patch adds CONFIG_SERVERIP_FROM_PROXYDHCP (default false) to enable this behavior and CONFIG_SERVERIP_FROM_PROXYDHCP_DELAY_MS (default 100) which tells u-boot to wait additional time after receiving the main DHCP response to give the ProxyDHCP response time to arrive - The PXE spec for ProxyDHCP is more complicated than the solution added here as diagramed on page 16: http://www.pix.net/software/pxeboot/archive/pxespec.pdf: ``` DHCP Discover will be retried four times. The four timeouts are 4, 8, 16 and 32 seconds respectively. If a DHCPOFFER is received without an Option timeouts in an attempt to receive a PXE response. ``` - Adding a simple delay worked for my purposes but let me know if a more robust solution is required Signed-off-by: Lyle Franklin <lylejfranklin(a)gmail.com> --- net/Kconfig | 14 ++++++++++++++ net/bootp.c | 27 ++++++++++++++++++++++----- 2 files changed, 36 insertions(+), 5 deletions(-) diff --git a/net/Kconfig b/net/Kconfig index 68cecf75a2..e46eb7833a 100644 --- a/net/Kconfig +++ b/net/Kconfig @@ -35,4 +35,18 @@ config TFTP_BLOCKSIZE help Default TFTP block size. +config SERVERIP_FROM_PROXYDHCP + bool "Get serverip value from Proxy DHCP response" + help + Allows bootfile config to be fetched from Proxy DHCP server + while IP is obtained from main DHCP server. + +config SERVERIP_FROM_PROXYDHCP_DELAY_MS + int "# of additional milliseconds to wait for ProxyDHCP response" + default 100 + help + Amount of additional time to wait for ProxyDHCP response after + receiving response from main DHCP server.

[U-Boot] Booting on RK3399
by Simon Glass 19 Nov '20

19 Nov '20

Hi Kever, I have a firefly-rk3399 and would like to boot it into U-Boot (as a start) from an uSD card. Are there instructions somewhere on how to do this? I gather that I need OP-TEE but not how to build it or how to put the image together. I would like to have instructions in README.rockchip if possible. I'm planning to add U-Boot support for bob and maybe kevin (both Chromebooks) but am not sure where to start. I thought the firefly might be best since it is pretty common. Thanks for any help you can provide. Regards, Simon

[PATCH v2 00/10] net: ti: icssg: Add prueth support
by Keerthy 26 Oct '20

26 Oct '20

The series adds support for icssg_prueth functionality on u-boot. This series is based on top of master branch. rproc init needs to be done from uboot command prompt. The pru/rtu firmware loading is done by prueth driver soon after config paramters are setup. Currently only slice0/1 of icssg2 instance on am6-evm is supported. i.e Both slices of icssg2 instance are supported. Prebuilt firmware can be obtained from AM65 procSDK [1] rootfs at /lib/firmware/ti-pruss/am65x*.elf [1] http://software-dl.ti.com/processor-sdk-linux/esd/AM65X/latest/index_FDS.ht… This tests tftp on prueth. Note: Uboot ethernet driver architecture supports once instance per probe. So only one of the ports are supported per instance. So DT of prueth node should have either ethernet-mii0 or ethernet-mii1. Changes in v2: It has been a while since v1 was posted. Here are the changes: * Removed the usage of misc_init_by_ofnode instead used uclass_get_device_by_ofnode. * Introduced started variable to keep track of the status of the prueth device. * Build Tested on Travis: https://travis-ci.org/Keerthyj/u-boot/builds/651449684 Keerthy (10): net: eth-uclass: eth_get_dev based on SEQ_ALIAS instead of probe order soc: ti: pruss: add a misc driver for PRUSS in TI SoCs remoteproc: pruss: add PRU remoteproc driver net: ti: icssg-prueth: Add ICSSG ethernet driver arm: dts: k3-am65-main: Add msmc_ram node arm: dts: k3-am654-base-board-u-boot: Add icssg specific msmc_ram carveout nodes arm: dts: k3-am65-main: Add scm_conf node arm: dts: k3-am65-main: Add pruss nodes for ICSSG2 arm64: dts: ti: am654-base-board: add ICSSG2 Ethernet support configs: am65x_evm_a53_defconfig: Enable CONFIG_TI_AM64_ICSSG_PRUETH arch/arm/dts/k3-am65-main.dtsi | 191 ++++++ arch/arm/dts/k3-am65.dtsi | 4 +- arch/arm/dts/k3-am654-base-board-u-boot.dtsi | 129 ++++ configs/am65x_evm_a53_defconfig | 3 + drivers/net/ti/Kconfig | 8 + drivers/net/ti/Makefile | 1 + drivers/net/ti/icssg-prueth.c | 652 +++++++++++++++++++ drivers/net/ti/icssg.h | 36 + drivers/net/ti/icssg_classifier.c | 396 +++++++++++ drivers/remoteproc/Kconfig | 11 + drivers/remoteproc/Makefile | 1 + drivers/remoteproc/pru_rproc.c | 405 ++++++++++++ drivers/soc/ti/Kconfig | 12 + drivers/soc/ti/Makefile | 1 + drivers/soc/ti/pruss.c | 152 +++++ include/ti-pruss.h | 17 + net/eth-uclass.c | 12 +- 17 files changed, 2027 insertions(+), 4 deletions(-) create mode 100644 drivers/net/ti/icssg-prueth.c create mode 100644 drivers/net/ti/icssg.h create mode 100644 drivers/net/ti/icssg_classifier.c create mode 100644 drivers/remoteproc/pru_rproc.c create mode 100644 drivers/soc/ti/pruss.c create mode 100644 include/ti-pruss.h -- 2.17.1
